 Usage
 ------------------------------------------------------------------------------
 
-Just define a `.netlifyheaders` and/or a `.netlifyredirects` file in the root of your project and this
+### .netlifyheaders and/or .netlifyredirects
+
+There are a few ways to use this addon. The first one is to define a `.netlifyheaders` 
+and/or a `.netlifyredirects` file in the root of your project and this
 addon will copy the output to `dist/_headers` and `dist/_redirects` respectively.
 
+### ember-cli-build.js
+
+The second way is to define an `ember-cli-netlify` hash in your `ember-cli-build.js`.
+You can combine these methods, and anything defined in the config hash will be
+appended to the existing files. Currently, only redirects are supported, not headers.
+
+```js
+'ember-cli-netlify': {
+  redirects: [
+    'https://blog.shipshape.io/* https://shipshape.io/blog/:splat 301!',
+    'https://blog.shipshape.io/* https://shipshape.io/blog/:splat 301!'
+  ]
+}
+```
+
+### Using in an addon
+
+The final option, for addon authors, is to declare redirects for ember-cli-netlify during compilation. 
+To do so, you will want to:
+
+* Add `"ember-cli-netlify-plugin"` to your addon's package.json keywords array.
+* Define a `netlifyRedirects()` function in your addon's main file, that returns an array of redirects.
+* Advise your addon's users to install & configure `ember-cli-netlify` in the host application.
