# Nerves Toolchain: riscv64_nerves_linux_gnu
[](https://hex.pm/packages/nerves_toolchain_riscv64_nerves_linux_gnu)
This is a Nerves Toolchain repository.
If you're just trying to use Nerves (i.e., not adding support for a new
target), you don't need to use this directly. In fact, even if you're
developing for a new target, we may already have a cross-compiler available.
This project's purpose is to contain the information for hex.pm so that Nerves
cross-compilers can be referenced in `mix`. See
[nerves-toolchain](https://github.com/nerves-project/nerves-toolchain) for
the scripts used to generate the actual cross-compiler.
