 List of library dependencies to install (space separated). Default `""`.
 
+### `github-token`
+
+GitHub access token used to get information from the GitHub API. Only needed if you're using the size report features with private repositories. It will be convenient to use [`${{ secrets.GITHUB_TOKEN }}`](https://help.github.com/en/actions/configuring-and-managing-workflows/authenticating-with-the-github_token). Default `""`.
+
+### `size-report-sketch`
+
+Name of the sketch used to compare memory usage change. Default `""`.
+
+### `enable-size-deltas-report`
+
+Set to `true` to cause the action to determine the change in memory usage for the [`size-reports-sketch`](#size-reports-sketch) between the pull request branch and the tip of the pull request's base branch. This may be used with the [`arduino/actions/libraries/report-size-deltas` action](https://github.com/arduino/actions/tree/master/libraries/report-size-deltas). Default `false`.
+
+### `size-deltas-report-folder-name`
+
+Folder to save the JSON formatted memory usage change reports to. Should be used only to store reports. It will be created under [`GITHUB_WORKSPACE`](https://help.github.com/en/actions/configuring-and-managing-workflows/using-environment-variables). The folder will be created if it doesn't already exist. Default `"size-deltas-reports"`.
+
+### `enable-size-trends-report`
+
+Set to `true` to cause the action to record the memory usage of [`size-reports-sketch`](#size-reports-sketch) to a Google Sheets spreadsheet on every push to the repository's default branch. Default `false`.
+
+### `keyfile`
+
+Contents of the Google key file used to update the size trends report Google Sheets spreadsheet. This should be defined using a [GitHub secret](https://help.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets). Default `""`.
+1. Open https://console.developers.google.com/project
+1. Click the "Create Project" button.

+1. Click the button with the three horizontal lines at the top left corner of the window.
+1. Hover the mouse pointer over "APIs & Services".
+1. Click "Library".
+1. Make sure the name of the project you created is selected from the dropdown menu at the top of the window.
+1. Click 'Google Sheets API".
+1. Click the "Enable" button.
+1. Click the "Create Credentials" button.
+1. From the "Which API are you using?" menu, select "Google Sheets API".

+1. Click the "Add a new secret" link.
+1. In the "Name" field, enter the variable name you want to use for your secret. This will be used for the `size-trends-report-key-file` argument of the `compile-examples` action in your workflow configuration file. For example, if you named the secret `GOOGLE_KEY_FILE`, you would reference it in your workflow configuration as `${{ secrets.GOOGLE_KEY_FILE }}`.
+1. In the "Value" field, paste the contents of the key file.
+1. Click the "Add secret" button.
+1. Open the downloaded key file again.

 ## Example usage
 
+Only compiling examples:
+```yaml
+- uses: arduino/actions/libraries/compile-examples@master
+  with:
+    fqbn: 'arduino:avr:uno'
+```
+
+Storing the memory usage change report as a [workflow artifact](https://help.github.com/en/actions/configuring-and-managing-workflows/persisting-workflow-data-using-artifacts):
+```yaml
+- uses: arduino/actions/libraries/compile-examples@master

+    size-report-sketch: Foobar
+    enable-size-deltas-report: true
+- if: github.event_name == 'pull_request'
+  uses: actions/upload-artifact@v1
+  with:
+    name: size-deltas-reports
+    path: size-delta-reports
+```
+
+Publishing memory usage trends data to a Google Sheets spreadsheet:
 ```yaml
