 ## Usage
 
-In addition to the default `GITHUB_TOKEN`, the action requires a `repo` scoped token in order to commit.

+Alternatively, branches can be suffixed with a timestamp by setting the environment variable `BRANCH_SUFFIX` to the value `timestamp`. This option may be necessary if multiple pull requests will be created during the execution of a workflow.

+e.g.
+```
+create-pull-request/patch-1569322532
+create-pull-request/patch-1569322552

 #### Ignoring files
 
 If there are files or directories you want to ignore you can simply add them to a `.gitignore` file at the root of your repository. The action will respect this file.
