We'd love to accept your patches and contributions to this project. There are
just a few small guidelines you need to follow.
## Project Goals
In addition to the aims listed at the top of the [README](README.md) Snappy
explicitly supports the following:
1. C++11
2. Clang (gcc and MSVC are best-effort).
3. Low level optimizations (e.g. assembly or equivalent intrinsics) for:
1. [x86](https://en.wikipedia.org/wiki/X86)
2. [x86-64](https://en.wikipedia.org/wiki/X86-64)
3. ARMv7 (32-bit)
4. ARMv8 (AArch64)
4. Supports only the Snappy compression scheme as described in
[format_description.txt](format_description.txt).
5. CMake for building
Changes adding features or dependencies outside of the core area of focus listed
above might not be accepted. If in doubt post a message to the
[Snappy discussion mailing list](https://groups.google.com/g/snappy-compression).
