 #### Hooks
 
 Hooks will run when calling `release`. Hooks run only if a release will be triggered. 
+You can define hooks which run before or after the release. The shell commands will run in order, you can access the current release version via 
+an environment variable `RELEASE_VERSION` 
+
+```yml
+hooks:
+  preRelease:
+  - name: echo $RELEASE_VERSION
+  postRelease:

+
+#### Integrations
+
+Integrations are simple helpers to make integration with existing tools easier.
+At the moment npm is supported, the integration will set the version before release to the `package.json`
+```yml

+This will write all changes beginning from the last git tag til HEAD to a changelog file. 
+Default changelog file name if nothing is given via `--file`: `CHANGELOG.md`.
+Note that per default the new changelog will be prepended to the existing file.
+With `--max-file-size` a maximum sizes of the changelog file in megabytes can be specified.
+If the size exceeds the limit, the current changelog file will be moved to a new file called `<filename>-<1-n>.<file extension>`. The new changelog will be written to the `<filename>`.
