+# Contribute to this site
+
+This documentation site is built using [mdBook](https://rust-lang.github.io/mdBook/) and deployed to GitHub Pages. Changes merged into the `main` branch will automatically be built and deployed.
+
+Documentation can be edited directly in the GitHub web UI for existing pages. To create a new page, be sure to update `SUMMARY.md` as well. Once you're done with your changes, open a pull request for review.
+
+To understand more about how mdBook works, learn about the [anatomy of a book](https://rust-lang.github.io/mdBook/guide/creating.html#anatomy-of-a-book). One caveat for this repo is that the docs live at the root of the repo instead of in a `src/` folder.
+
+## Developing locally
+
+To build the site locally, clone this repository and install `mdbook` (follow the [official installation instructions](https://rust-lang.github.io/mdBook/guide/installation.html))[^1].
+
+Once installed, use the `mdbook` command-line tool from the root of this repo. For example, to automatically start watching, building, and serving the site:
+
+```shell
+mdbook serve
+```
+
+Then make your changes, preview them in your web browser (at [http://localhost:3000](http://localhost:3000) by default), commit, push, and open a pull request like any other git project. 
+
+[^1]: Alternatively, download the binary from the [GitHub releases](https://github.com/rust-lang/mdBook/releases), unpack it, and drop it into `bin/` in this repo (which is .gitignored). Then prefix your `mdbook` commands with the path, e.g. `bin/mdbook serve`.
