 Installing
 ----------
 Installing Handlebars is easy. Simply download the package [from the
 official site](http://handlebarsjs.com/) and add it to your web pages
 (you should usually use the most recent version).
 
+Alternatively, if you prefer having the latest version of handlebars from
+the 'master' branch, passing builds of the 'master' branch are automatically
+published to S3. You may download the latest passing master build by grabbing
+a `handlebars-latest.js` file from the [builds page][builds-page]. When the
+build is published, it is also available as a `handlebars-gitSHA.js` file on
+the builds page if you need a version to refer to others.
+`handlebars-runtime.js` builds are also available.
+
+**Note**: The S3 builds page is provided as a convenience for the community,
+but you should not use it for hosting Handlebars in production.
