+# Generated gpiosim Rust FFI bindings
+Automatically generated Rust FFI bindings via
+	[bindgen](https://github.com/rust-lang/rust-bindgen).
+
+## Updating bindings
+1. Clone the source from
+	<https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/>
+2. run `cd libgpiod/bindings/rust/gpiosim/`
+2. run `cargo build --features generate`
+3. Copy the bindings 'cp ../target/debug/build/gpiosim-###/out/bindings.rs src/bindings.rs'
+4. Commit changes in `src/bindings.rs`
