+   has been advised of the possibility of such damages.
-the conditions stated below.  Sublicensing is not allowed; section 10
+
-makes it unnecessary.
+9. Accepting Warranty or Additional Liability. While redistributing

+   the Work or Derivative Works thereof, You may choose to offer,
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+   and charge a fee for, acceptance of support, warranty, indemnity,
-
+   or other liability obligations and/or rights consistent with this
-  No covered work shall be deemed part of an effective technological
+   License. However, in accepting such obligations, You may act only
-measure under any applicable law fulfilling obligations under article
+   on Your own behalf and on Your sole responsibility, not on behalf

+   of any other Contributor, and only if You agree to indemnify,

+   defend, and hold each Contributor harmless for any liability
-measures.
+   incurred by, or claims asserted against, such Contributor by reason
-
+   of your accepting any such warranty or additional liability.
  When you convey a covered work, you waive any legal power to forbid
 circumvention of technological measures to the extent such circumvention
 is effected by exercising rights under this License with respect to
 the covered work, and you disclaim any intention to limit operation or
 modification of the work as a means of enforcing, against the work's
 users, your or third parties' legal rights to forbid circumvention of
 technological measures.
  4. Conveying Verbatim Copies.
  You may convey verbatim copies of the Program's source code as you
 receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice;
 keep intact all notices stating that this License and any
 non-permissive terms added in accord with section 7 apply to the code;
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.
  You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.
  5. Conveying Modified Source Versions.
  You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these conditions:
    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.
    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".
    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.
    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.
  A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation's users
 beyond what the individual works permit.  Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.
  6. Conveying Non-Source Forms.
  You may convey a covered work in object code form under the terms
 of sections 4 and 5, provided that you also convey the
 machine-readable Corresponding Source under the terms of this License,
 in one of these ways:
    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.
    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.
    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.
    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.
    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.
  A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.
  A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal, family,
 or household purposes, or (2) anything designed or sold for incorporation
 into a dwelling.  In determining whether a product is a consumer product,
 doubtful cases shall be resolved in favor of coverage.  For a particular
 product received by a particular user, "normally used" refers to a
 typical or common use of that class of product, regardless of the status
 of the particular user or of the way in which the particular user
 actually uses, or expects or is expected to use, the product.  A product
 is a consumer product regardless of whether the product has substantial
 commercial, industrial or non-consumer uses, unless such uses represent
 the only significant mode of use of the product.
  "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to install
 and execute modified versions of a covered work in that User Product from
 a modified version of its Corresponding Source.  The information must
 suffice to ensure that the continued functioning of the modified object
 code is in no case prevented or interfered with solely because
 modification has been made.
  If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information.  But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).
  The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or updates
 for a work that has been modified or installed by the recipient, or for
 the User Product in which it has been modified or installed.  Access to a
 network may be denied when the modification itself materially and
 adversely affects the operation of the network or violates the rules and
 protocols for communication across the network.
  Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.
  7. Additional Terms.
  "Additional permissions" are terms that supplement the terms of this
 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law.  If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.
  When you convey a copy of a covered work, you may at your option
 remove any additional permissions from that copy, or from any part of
 it.  (Additional permissions may be written to require their own
 removal in certain cases when you modify the work.)  You may place
 additional permissions on material, added by you to a covered work,
 for which you have or can give appropriate copyright permission.
  Notwithstanding any other provision of this License, for material you
 add to a covered work, you may (if authorized by the copyright holders of
 that material) supplement the terms of this License with terms:
    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or
    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or
    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or
    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or
    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or
    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.
  All other non-permissive additional terms are considered "further
 restrictions" within the meaning of section 10.  If the Program as you
 received it, or any part of it, contains a notice stating that it is
 governed by this License along with a term that is a further
 restriction, you may remove that term.  If a license document contains
 a further restriction but permits relicensing or conveying under this
 License, you may add to a covered work material governed by the terms
 of that license document, provided that the further restriction does
 not survive such relicensing or conveying.
  If you add terms to a covered work in accord with this section, you
 must place, in the relevant source files, a statement of the
 additional terms that apply to those files, or a notice indicating
 where to find the applicable terms.
  Additional terms, permissive or non-permissive, may be stated in the
 form of a separately written license, or stated as exceptions;
 the above requirements apply either way.
  8. Termination.
  You may not propagate or modify a covered work except as expressly
 provided under this License.  Any attempt otherwise to propagate or
 modify it is void, and will automatically terminate your rights under
 this License (including any patent licenses granted under the third
 paragraph of section 11).
  However, if you cease all violation of this License, then your
 license from a particular copyright holder is reinstated (a)
 provisionally, unless and until the copyright holder explicitly and
 finally terminates your license, and (b) permanently, if the copyright
 holder fails to notify you of the violation by some reasonable means
 prior to 60 days after the cessation.
  Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
  Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, you do not qualify to receive new licenses for the same
 material under section 10.
  9. Acceptance Not Required for Having Copies.
  You are not required to accept this License in order to receive or
 run a copy of the Program.  Ancillary propagation of a covered work
 occurring solely as a consequence of using peer-to-peer transmission
 to receive a copy likewise does not require acceptance.  However,
 nothing other than this License grants you permission to propagate or
 modify any covered work.  These actions infringe copyright if you do
 not accept this License.  Therefore, by modifying or propagating a
 covered work, you indicate your acceptance of this License to do so.
  10. Automatic Licensing of Downstream Recipients.
  Each time you convey a covered work, the recipient automatically
 receives a license from the original licensors, to run, modify and
 propagate that work, subject to this License.  You are not responsible
 for enforcing compliance by third parties with this License.
  An "entity transaction" is a transaction transferring control of an
 organization, or substantially all assets of one, or subdividing an
 organization, or merging organizations.  If propagation of a covered
 work results from an entity transaction, each party to that
 transaction who receives a copy of the work also receives whatever
 licenses to the work the party's predecessor in interest had or could
 give under the previous paragraph, plus a right to possession of the
 Corresponding Source of the work from the predecessor in interest, if
 the predecessor has it or can get it with reasonable efforts.
  You may not impose any further restrictions on the exercise of the
 rights granted or affirmed under this License.  For example, you may
 not impose a license fee, royalty, or other charge for exercise of
 rights granted under this License, and you may not initiate litigation
 (including a cross-claim or counterclaim in a lawsuit) alleging that
 any patent claim is infringed by making, using, selling, offering for
 sale, or importing the Program or any portion of it.
  11. Patents.
  A "contributor" is a copyright holder who authorizes use under this
 License of the Program or a work on which the Program is based.  The
 work thus licensed is called the contributor's "contributor version".
  A contributor's "essential patent claims" are all patent claims
 owned or controlled by the contributor, whether already acquired or
 hereafter acquired, that would be infringed by some manner, permitted
 by this License, of making, using, or selling its contributor version,
 but do not include claims that would be infringed only as a
 consequence of further modification of the contributor version.  For
 purposes of this definition, "control" includes the right to grant
 patent sublicenses in a manner consistent with the requirements of
 this License.
  Each contributor grants you a non-exclusive, worldwide, royalty-free
 patent license under the contributor's essential patent claims, to
 make, use, sell, offer for sale, import and otherwise run, modify and
 propagate the contents of its contributor version.
  In the following three paragraphs, a "patent license" is any express
 agreement or commitment, however denominated, not to enforce a patent
 (such as an express permission to practice a patent or covenant not to
 sue for patent infringement).  To "grant" such a patent license to a
 party means to make such an agreement or commitment not to enforce a
 patent against the party.
  If you convey a covered work, knowingly relying on a patent license,
 and the Corresponding Source of the work is not available for anyone
 to copy, free of charge and under the terms of this License, through a
 publicly available network server or other readily accessible means,
 then you must either (1) cause the Corresponding Source to be so
 available, or (2) arrange to deprive yourself of the benefit of the
 patent license for this particular work, or (3) arrange, in a manner
 consistent with the requirements of this License, to extend the patent
 license to downstream recipients.  "Knowingly relying" means you have
 actual knowledge that, but for the patent license, your conveying the
 covered work in a country, or your recipient's use of the covered work
 in a country, would infringe one or more identifiable patents in that
 country that you have reason to believe are valid.
  If, pursuant to or in connection with a single transaction or
 arrangement, you convey, or propagate by procuring conveyance of, a
 covered work, and grant a patent license to some of the parties
 receiving the covered work authorizing them to use, propagate, modify
 or convey a specific copy of the covered work, then the patent license
 you grant is automatically extended to all recipients of the covered
 work and works based on it.
  A patent license is "discriminatory" if it does not include within
 the scope of its coverage, prohibits the exercise of, or is
 conditioned on the non-exercise of one or more of the rights that are
 specifically granted under this License.  You may not convey a covered
 work if you are a party to an arrangement with a third party that is
 in the business of distributing software, under which you make payment
 to the third party based on the extent of your activity of conveying
 the work, and under which the third party grants, to any of the
 parties who would receive the covered work from you, a discriminatory
 patent license (a) in connection with copies of the covered work
 conveyed by you (or copies made from those copies), or (b) primarily
 for and in connection with specific products or compilations that
 contain the covered work, unless you entered into that arrangement,
 or that patent license was granted, prior to 28 March 2007.
  Nothing in this License shall be construed as excluding or limiting
 any implied license or other defenses to infringement that may
 otherwise be available to you under applicable patent law.
  12. No Surrender of Others' Freedom.
  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot convey a
 covered work so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you may
 not convey it at all.  For example, if you agree to terms that obligate you
 to collect a royalty for further conveying from those to whom you convey
 the Program, the only way you could satisfy both those terms and this
 License would be to refrain entirely from conveying the Program.
  13. Remote Network Interaction; Use with the GNU General Public License.
  Notwithstanding any other provision of this License, if you modify the
 Program, your modified version must prominently offer all users
 interacting with it remotely through a computer network (if your version
 supports such interaction) an opportunity to receive the Corresponding
 Source of your version by providing access to the Corresponding Source
 from a network server at no charge, through some standard or customary
 means of facilitating copying of software.  This Corresponding Source
 shall include the Corresponding Source for any work covered by version 3
 of the GNU General Public License that is incorporated pursuant to the
 following paragraph.
  Notwithstanding any other provision of this License, you have
 permission to link or combine any covered work with a work licensed
 under version 3 of the GNU General Public License into a single
 combined work, and to convey the resulting work.  The terms of this
 License will continue to apply to the part which is the covered work,
 but the work with which it is combined will remain governed by version
 3 of the GNU General Public License.
  14. Revised Versions of this License.
  The Free Software Foundation may publish revised and/or new versions of
 the GNU Affero General Public License from time to time.  Such new versions
 will be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.
  Each version is given a distinguishing version number.  If the
 Program specifies that a certain numbered version of the GNU Affero General
 Public License "or any later version" applies to it, you have the
 option of following the terms and conditions either of that numbered
 version or of any later version published by the Free Software
 Foundation.  If the Program does not specify a version number of the
 GNU Affero General Public License, you may choose any version ever published
 by the Free Software Foundation.
  If the Program specifies that a proxy can decide which future
 versions of the GNU Affero General Public License can be used, that proxy's
 public statement of acceptance of a version permanently authorizes you
 to choose that version for the Program.
  Later license versions may give you additional or different
 permissions.  However, no additional obligations are imposed on any
 author or copyright holder as a result of your choosing to follow a
 later version.
  15. Disclaimer of Warranty.
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  16. Limitation of Liability.
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 SUCH DAMAGES.
  17. Interpretation of Sections 15 and 16.
  If the disclaimer of warranty and limitation of liability provided
 above cannot be given local legal effect according to their terms,
 reviewing courts shall apply local law that most closely approximates
 an absolute waiver of all civil liability in connection with the
 Program, unless a warranty or assumption of liability accompanies a
 copy of the Program in return for a fee.
 END OF TERMS AND CONDITIONS
 --------------------------------------------------------------------------------
                          ADDITIONAL TERMS
 --------------------------------------------------------------------------------

+**This repository is not used anymore. Development of Orca was moved here: [https://github.com/orca-app/orca](https://github.com/orca-app/orca)**
 **DISCLAIMER: This project is very much a Work In Progress. We are making it accessible in this very early state so that participants in the [2023 Wheel Reinvention Jam](https://handmade.network/jam/2023) can try it out and possibly use it as their jamming platform. Expect bugs, missing and/or incomplete features, unstable APIs, and sparse documentation. Some current issues might be a show stopper for you, so make sure you can build and run the sample apps before jumping in.**
 **If you do choose to try out Orca anyway, thank you! We'll do our best to answer your questions, and we'd really appreciate your feedback!**
 ------
 # Orca
 Orca is a development platform and runtime environment for cross-platform, sandboxed graphical WebAssembly applications. In this early MVP you can:
 - Receive mouse and keyboard input.
 - Draw paths, images and text using a 2D vector graphics API.
 - Draw 2D/3D graphics using OpenGL ES 3.1 (minus a few features)
 - Build user interfaces using our UI API and default widgets.
 - Read and write files using a capability-based API.
 ## Installing
 The Orca command-line tools must be installed to your system in order to use them in your own projects.
 **At this early stage, you must build Orca yourself - in the future, this installation process will be streamlined.**
 ### Requirements
 - Windows or Mac (Linux is not yet supported)
 - [Python 3](https://www.python.org/) (for command line tools)
 - Clang
 	- **Windows users:** `clang` can be installed via the Visual Studio installer. Search for "C++ Clang Compiler".
 	- **Mac users:** Apple's built-in `clang` does not support WebAssembly. We recommend installing `clang` via [Homebrew](https://brew.sh/) with `brew install clang`.
 - MSVC (Visual Studio 2022 17.5 or newer) (Windows only)
 	- This can be installed through the [Visual Studio Community](https://visualstudio.microsoft.com/) installer.
 	- Please note the version requirement! Orca requires C11 atomics, which were only added to MSVC in late 2022.
 ### Installation instructions
 Clone the repo, then `cd` into the `orca` directory:
 ```
 git clone git@git.handmade.network:hmn/orca.git
 cd orca
 ```
 Build the Orca runtime:
 ```
 ./orca dev build-runtime
 ```
 Install the Orca dev tools. If on Windows, the tool can automatically add `orca` to your PATH. Otherwise, you must manually add the Orca install directory to your PATH, e.g. by updating `.zshrc` or `.bashrc`.
 ```
 ./orca dev install
 ```
 Finally, verify that Orca is successfully installed by running the `orca version` command. Note the lack of `./`!
 ```
 orca version
 ```
 If you encounter any errors, see the FAQ below.
 Once the `orca` tools are installed, you can use them from anywhere to
 ### Building the sample Orca apps
 The `samples` directory contains several sample apps that demonstrate various Orca features. To build one, `cd` to a sample project's directory and run its build script. For example, for the `breakout` sample:
 ```
 cd samples/breakout
 # Windows
 build.bat
 # Mac
 ./build.sh
 ```
 On Windows this creates a `Breakout` directory in `samples/breakout`. You can launch the app by running `Breakout/bin/Breakout.exe`. On macOS this creates a `Breakout.app` bundle in `samples/breakout` that you can double-click to run.
 ## Writing an Orca app
 Orca apps are WebAssembly modules that use the Orca APIs. The process for creating an Orca application is:
 1. Compile a WebAssembly module using your language and toolchain of choice.
 2. Bundle the WebAssembly module into a native executable using the Orca command-line tools.
 For a more thorough overview, please read the [Quick Start Guide](./doc/QuickStart.md), which will walk you through building a simple application.
 The following additional resources may also help you familiarize yourself with Orca and its APIs:
 - The [samples folder](./samples) contains sample applications that show various aspects of the Orca API and support library:
 	- [`breakout`](./samples/breakout) is a small breakout game making use of the vector graphics API.
 	- [`clock`](./samples/clock) is a simple clock showcasing vector graphics and the time API.
 	- [`triangle`](./samples/triangle) shows how to draw a spinning triangle using the GLES API.
 	- [`fluid`](./samples/fluid) is a fluid simulation using a more complex GLES setup.
 	- [`ui`](./samples/ui) showcases the UI API and Orca's default UI widgets.  
 - The [API Cheatsheets](./doc/cheatsheets) provide a list of Orca API functions, grouped by topic.
 ## FAQ
 **What platforms does Orca supports?**
 We currently support Windows 10 and up, and macOS 10.15 and up.
 **What languages can I use with Orca?**
 In principle, you can use any language and toolchain that can produce a WebAssembly module and bind to the Orca APIs. However, several important parts of Orca, such as the UI, are provided as part of the support library, which must be compiled to WebAssembly with you app, and is written in C. Therefore, at this early stage, it may be difficult to use any language other than C.
 C-style C++ is possible but requires compiling the support library in C as a separate object file, and then adding that object to your compile command when building your app.
 We're currently working with contributors to add support for Odin and Zig, and we look forward to expanding the number of officially-supported languages in the future. 
 **I am getting errors about atomics when building the runtime on Windows.**
 Please ensure that you have the latest version of Visual Studio and MSVC installed. The Orca runtime requires the use of C11 atomics, which were not added to MSVC until late 2022.
 **I am getting errors saying that `orca` is not found.**
 Please ensure that you have installed Orca to your system per the installation instructions above. Please also ensure that the Orca install directory is on your PATH. The installation path is printed when running `./orca dev install`.
 ## License
 Orca is distributed under the terms of the GNU Affero General Public License version 3, with additional terms in accordance with section 7 of AGPLv3. These additional terms ensure that:
 - Modified versions of Orca must reasonably inform users that they are modified.
 - You can distribute your application's WebAssembly modules under the terms of your choice, and are not required to license them under the terms of the AGPLv3.

+This is a short introduction to developing an application that can be run by the Orca runtime. We'll present the basic structure of an Orca application, and walk through a simple example in C.
 ## What is an Orca app?
 An Orca app is a WebAssembly module designed for the Orca runtime. Your app interacts with the Orca runtime via WebAssembly imports and exports. For example, you can import functions from the Orca runtime to get user input, and export functions to the Orca runtime to draw to the screen.
 Orca also ships with a core library, written in C, which facilitates interaction with the Orca runtime and provides features like UI. This library should be compiled along with your app as part of producing your WebAssembly module.
 You can, in principle, write an Orca app in any programming language that supports WebAssembly. However, at this early stage, C is the only officially supported language.
 ![Basic structure of a C app](images/app_c.png)
 Once you have compiled your WebAssembly module, you can bundle this module into an executable using the `orca bundle` command. The application bundle can include images, fonts, or any other private data that the app needs in order to function. These files can be read or written from the app without asking the user for permission. The resulting Orca executables are therefore self-contained.
 ![Example Orca application bundle](images/app_bundle.png)
 ## Basic structure
 Orca exposes a number of types and functions to applications. In order to use them the first thing to do is to include `orca.h`.
-```
+```c
 #include<orca.h>
 ```
 The Orca runtime manages the application's window and event loop. In order to receive a specific kind of event, you can define an associated _event handler_ and export it to the runtime. For instance, to be notified when your application's window is resized, you should define the `oc_on_resize()` handler:
-```
+```c
 ORCA_EXPORT void oc_on_resize(u32 width, u32 height)
 {
 	// handle the window resize event
 }
 ```
-The `ORCA_EXPORT` macro makes the handler visible to the orca runtime, which automatically binds it to the window resize event.
+The `ORCA_EXPORT` macro makes the handler visible to the Orca runtime, which automatically binds it to the window resize event.
-Handlers are optional. If you don't care about an event, you can just omit the associated handler. You probably want to define at least two important handlers:
+Handlers are optional. If you don't care about an event, you can just omit the associated handler. However, you will almost certainly want to define at least two important handlers:
- `oc_on_init()` is called once when your application starts and can be use to initialize your application's resources
+- `oc_on_init()` is called once when your application starts and can be use to initialize your application's resources.
 - `oc_on_frame_refresh()` is called when your application needs to render a new frame, typically tied to the refresh rate of the monitor.
 For a list of available handlers and their signatures, see the [app cheatsheet](../doc/cheatsheets/cheatsheet_app.h).
-## Clock Example
+## Clock example
 Let's look at the [clock example](../samples/clock). This is a simple app that shows an analog clock and showcases a couple of interesting Orca APIs.
-Open [`main.c`](../samples/clock/src/main.c) and look at the definition of `oc_on_init()`. This handler is called when the applications starts, right after the application window has been created.
+Open [`main.c`](../samples/clock/src/main.c) and look at the definition of `oc_on_init()`. This handler is called when the application starts, right after the application window has been created.
 The first thing we do here is set the title and dimensions of the window. We then create the graphics resources that we'll use to draw the clock onto the window.
 ```c
 ORCA_EXPORT void oc_on_init(void)
 {
    oc_window_set_title(OC_STR8("clock"));
    oc_window_set_size((oc_vec2){ .x = 400, .y = 400 });
    // ...
 }
 ```
 ### Graphics surfaces
-The next line of `oc_init()` creates a _graphics surface_. A surface represents a destination you can draw into using a specific API. In this sample, we're going to use a canvas surface, which allows drawing with a 2D vector graphics API. Other samples use a GLES surface to draw with the OpenGL ES API.

In this sample, we're going to use a canvas surface, which allows drawing with a 2D vector graphics API. Other samples use a GLES surface to draw with the OpenGL ES API.
 Before drawing into it, the surface must be selected as the current surface by calling `oc_surface_select()`. Once all drawing is done you can display the result by calling `oc_surface_present()`.
 ```c
 oc_surface surface = { 0 };
 oc_canvas canvas = { 0 };
 ORCA_EXPORT void oc_on_init(void)
 {
    // ...
    surface = oc_surface_canvas();
    canvas = oc_canvas_create();
    // ...
 }
 ```
 ### Canvas
 After creating the surface, we create a _canvas_. A canvas holds some context for drawing commands, like the current color or stroke width, as well as a command buffer that records all drawing commands. All canvas drawing functions use an implicit _current canvas_. You can select a canvas to be the current canvas by calling `oc_canvas_select()`, as seen at the begining of `oc_on_frame_refresh()`.

 Canvas drawing functions can be roughly divided into three groups:
 - Path functions like `oc_line_to()` or `oc_cubic_to()` are used to specify paths using lines and curves.
- Attributes setup functions like `oc_set_color()` or `oc_set_width()` are used to set attributes used by subsequent commands.
