+
+## CoC
+The [VideoLAN Code of Conduct](https://wiki.videolan.org/CoC) applies fully to this project.
+
+## ToDo
+
+The todo list can be found [on the wiki](https://code.videolan.org/videolan/dav1d/wikis/task-list).
+
+## Codebase language
+
+The codebase is developed with the following assumptions:
+
+For the library:
+- C language with C99 version, without the VLA or the Complex (*\_\_STDC_NO_COMPLEX__*) features, and without compiler extensions. Anonymous structures and unions are the only allowed compiler extensions for internal code.
+- x86 asm in .asm files, using the NASM syntax,
+- arm/arm64 in .S files, using the GAS syntax limited to subset llvm 5.0's internal assembler supports,
+- no C++ is allowed, whatever the version.
+
+For the tools and utils:
+- C *(see above for restrictions)*
+- Rust
+- C++ is only allowed for the MFT.
+
+If you want to use *Threads* or *Atomic* features, please conform to the **C11**/**POSIX** semantic and use a wrapper for older compilers/platforms *(like done in VLC)*.
+
+Please use modern standard POSIX functions *(strscpy, asprintf, tdestroy)*, and provide a compatibility fallback *(like done in VLC)*.
+
+We will make reasonable efforts for compilers that are a bit older, but we won't support gcc 3 or MSVC 2012.
+
+## Authorship
+
+Please provide a correct authorship for your commit logs, with a name and a valid email.
+
+We will reject anonymous contributions for now. As an exception, known pseudonyms from the multimedia community are accepted.

+
+## Commit logs
+
+Please read [How to Write a Git Commit Message](https://chris.beams.io/posts/git-commit/).
+
+## Submit requests (WIP)
+
+- Code,
+- [Compile](https://xkcd.com/303/),
+- Check your [code style](https://code.videolan.org/videolan/dav1d/wikis/Coding-style),
+- Test,
+- Try,
+- Submit patches through merge requests,
+- Check that this passes the CI.
