 There is an official Command-Line Interface for wavedrom that can easily be
 incorporated into scripts or workflows. This binary is available from the
 [GitHub releases](https://github.com/coastalwhite/wavedrom-rs/releases).
+
+A binary can be downloaded from here and be put into a location corresponding to
+a operating system.
+
+For Mac and Linux, `/usr/bin/local` is a good place to store the binary.
+
+## Compilation from source
+
+It is possible to compile from the GitHub directory. This generates the most
+up-to-date binary, but may be less stable. This requires `git` and the Rust
+toolchain `cargo` to be installed.
+
+```bash
+git clone https://github.com/coastalwhite/wavedrom-rs
+cargo install --path=./wavedrom
+```
