+# Dispensy Documentation
+
+You can find the [documentation here on GitHub pages](https://drinkrobotics.github.io/dispensy/).
+This file is intended for contributors that want to modify this website!
+
+## Local Build
+
+The docs are built using [mdbook](https://github.com/rust-lang/mdBook).
+Get the [latest release from GitHub](https://github.com/rust-lang/mdBook/releases) for a pre-built binary if you want to test changes to the docs locally.
+
+    mdbook serve --open docs
+
+This will open your browser to a local development instance of the docs.
