+# Rust Bindgen Rules
+
+<div class="toc">
+  <h2>Rules</h2>
+  <ul>
+    <li><a href="docs/index.md#rust_bindgen_toolchain">rust_bindgen_toolchain</a></li>
+    <li>rust_bindgen</li>
+    <li>rust_bindgen_library</li>
+  </ul>
+</div>
+
+## Overview
+
+These rules are for using [Bindgen][bindgen] to generate [Rust][rust] bindings to C (and some C++) libraries.
+
+[rust]: http://www.rust-lang.org/
+[bindgen]: https://github.com/rust-lang/rust-bindgen
+
+See the [bindgen example](../examples/ffi/rust_calling_c/simple/BUILD#L9) for a more complete example of use.
+
+### Setup
+
+To use the Rust bindgen rules, add the following to your `WORKSPACE` file to add the
+external repositories for the Rust bindgen toolchain (in addition to the [rust rules setup](..)):
+
+```python
+load("@io_bazel_rules_rust//bindgen:repositories.bzl", "rust_bindgen_repositories")
+
+rust_bindgen_repositories()
+```
+This makes the default toolchain defined in [`@io_bazel_rules_rust`](./BUILD) available.
+
+[raze]: https://github.com/google/cargo-raze
+
+It will load crate dependencies of bindgen that are generated using
+[cargo raze][raze] inside the rules_rust
+repository. However, using those dependencies might conflict with other uses
+of [cargo raze][raze]. If you need to change
+those dependencies, please see the [dedicated section below](#custom-deps).
+
+For additional information, see the [Bazel toolchains documentation](https://docs.bazel.build/versions/master/toolchains.html).
+
+## <a name="custom-deps">Customizing dependencies
+
+These rules depends on the [`bindgen`](https://crates.io/crates/bindgen) binary crate, and it 
+in turn depends on both a clang binary and the clang library. To obtain these dependencies,
+`rust_bindgen_repositories` imports bindgen and its dependencies using BUILD files generated with
+[`cargo raze`][raze], along with a tarball of clang.
+
+If you want to change the bindgen used, or use [`cargo raze`][raze] in a more
+complex scenario (with more dependencies), you must redefine those
+dependencies.
+
+To do this, once you've imported the needed dependencies (see our
+[Cargo.toml](./raze/Cargo.toml) file to see the default dependencies), you
+need to create your own toolchain. To do so you can create a BUILD
+file with your [`rust_bindgen_toolchain`](../docs/index.md#rust_bindgen_toolchain) definition, for example:
+
+```python
+load("@io_bazel_rules_rust//bindgen:bindgen.bzl", "rust_bindgen_toolchain")
+
+rust_bindgen_toolchain(
+    name = "bindgen-toolchain-impl",
+    bindgen = "//my/raze:cargo_bin_bindgen",
+    clang = "//my/clang:clang",
+    libclang = "//my/clang:libclang.so",
+    libstdcxx = "//my/cpp:libstdc++",
+)
+
+toolchain(
+    name = "bindgen-toolchain",
+    toolchain = "bindgen-toolchain-impl",
+    toolchain_type = "@io_bazel_rules_rust//bindgen:bindgen_toolchain",
+)
+```
+
+Now that you have your own toolchain, you need to register it by
+inserting the following statement in your `WORKSPACE` file:
+
+```python
+register_toolchains("//my/toolchains:bindgen-toolchain")
+```
