 | `GITHUB_TOKEN`  | In order for GitHub to trigger the rebuild of your page you must provide the action with the repositories provided GitHub token. This can be referenced in the workflow `yml` file by using `${{ secrets.GITHUB_TOKEN }}`. Only required if an access token is **not** provided. **Please note there is currently an issue affecting the use of this token, [you can learn more here](https://github.com/JamesIves/github-pages-deploy-action/issues/5)**. | `secrets / with` | **Yes** |
 | `BRANCH`  | This is the branch you wish to deploy to, for example `gh-pages` or `docs`.  | `with` | **Yes** |
 | `FOLDER`  | The folder in your repository that you want to deploy. If your build script compiles into a directory named `build` you'd put it here. **Folder paths cannot have a leading `/` or `./`**. If you wish to deploy the root directory you can place a `.` here. | `with` | **Yes** |
-| `BASE_BRANCH`  | The base branch of your repository which you'd like to checkout prior to deploying. This defaults to the current commit that triggered the build followed by `master`.  | `with` | **No** |
 | `TARGET_FOLDER`  | If you'd like to push the contents of the deployment folder into a specific directory on the deployment branch you can specify it here.  | `with` | **No** |
+| `BASE_BRANCH`  | The base branch of your repository which you'd like to checkout prior to deploying. This defaults to the current commit [SHA](http://en.wikipedia.org/wiki/SHA-1) that triggered the build followed by `master`. This is useful for making deployments from another branch, and also may be neccersary when using a scheduled job.  | `with` | **No** |
 | `CLEAN`  | If your project generates hashed files on build you can use this option to automatically delete them from the deployment branch with each deploy. This option can be toggled on by setting it to `true`.  | `with` | **No** |
 | `CLEAN_EXCLUDE`  | If you need to use `CLEAN` but you'd like to preserve certain files or folders you can use this option. This should be formatted as an array but stored as a string. For example: `'["filename.js", "folder"]'`  | `with` | **No** |
