+# ExoPlayer website #
+
+The [ExoPlayer website](https://exoplayer.dev/) is hosted on
+GitHub Pages, and is statically generated using Jekyll.
+
+* GitHub provides a guide describing how to setup a GitHub Pages site using
+  Jekyll
+  [here](https://help.github.com/articles/using-jekyll-as-a-static-site-generator-with-github-pages/).
+* GitHub provides a guide describing how to test changes to the site locally
+  [here](https://help.github.com/articles/setting-up-your-github-pages-site-locally-with-jekyll/).
+  Once your machine is setup, you can build and run a local instance of the
+  site using `./run_locally.sh` from the root directory.
