 They can be attached to different parts of each element type,

 or the parent blocks vs. sub-blocks of a block model.
+
+## Compiling
+
+First [install Rust](https://www.rust-lang.org/tools/install).
+Run `cargo build --all --release` in the root directory to build the release version of the Rust
+crate and C wrapper.
+The C wrapper build will place `omf.h` and the platform-specific shared library files
+(e.g.: `omfc.dll` and `omfc.dll.lib` for Windows) in `target/release`.
+
+You can the `--release` argument off to build a debug version.
+This may be useful for debugging C code that calls into OMF for example,
+but it will be slow.
+
+For the Rust tests, run `cargo test --all`.
+
+To build and run the C examples:
+
+1. Run `cargo build --all --release` first.
+2. Change directory into `omf-c/examples/`.
+3. Run `build.bat` on Windows or `build.sh` on Linux/MacOS.
+
+This will build all examples, run them, and compare the results to the benchmarks.
+
+## Documentation
+
+The documentation is built with [MkDocs](https://www.mkdocs.org/).
+To build locally:
+
+1. Create and activate a Python virtual environment.
+2. Change directory into `docs/`.
+3. Run `build.bat` on Windows or `build.sh` on Linux/MacOS.
+
+This will install the required dependencies, then build the file format, Rust, and C documentation into `site/`.
