# `prost-build`
`prost-build` makes it easy to generate Rust code from `.proto` files as part of
a Cargo build. See the crate [documentation](https://docs.rs/prost-build/) for examples
of how to integrate `prost-build` into a Cargo project.
## `protoc`
`prost-build` uses `protoc` to parse the proto files. There are two ways to make `protoc`
available for `prost-build`:
* Include `protoc` in your `PATH`. This can be done by following the [`protoc` install instructions].
* Pass the `PROTOC=<my/path/to/protoc>` environment variable with the path to
`protoc`.
[`protoc` install instructions]: https://github.com/protocolbuffers/protobuf#protocol-compiler-installation
