 This is the main source code repository for [Crab](https://github.com/crablang/crab). It contains the compiler,
 standard library, and documentation.

If you are looking for the renamed toolchain that simply mirrors upstream, check out [the stable branch](https://github.com/crablang/crab/tree/stable) and follow the instructions there.**
