+## default release notes
+
+The default release notes are a changelog based on the [AngularJS Commit Message Conventions](https://docs.google.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y/edit).
+
+## custom release notes
+
+If you want to generate your own release notes you can provide a generator in the `package.json`.
+
+Add a `release` field and provide a path where `semantic-release` can require your it:
+
+```json
+"release": {
+  "notes": "./lib/custom-release-notes"
+}
+```
+
+The module should export a function that calls the provided callback (the last and currently only argument) with an error object or `null` as the first argument and the release notes(string) as the second argument. 
+
+Have a look at [the default generator](https://github.com/boennemann/semantic-release/blob/master/lib/release-notes.js) for a sample implementation.
