 This [GitHub action](https://github.com/features/actions) will handle the  deploy process of your project to [GitHub Pages](https://pages.github.com/). It can be configured to upload your production-ready code into any branch you'd like, including `gh-pages` and `docs`.
 
+![Example Screenshot](screenshot.png)
+
 ## Getting Started :airplane:
 You can include the action in your workflow to trigger on any event that [GitHub actions supports](https://help.github.com/en/articles/events-that-trigger-workflows). If the remote branch that you wish to deploy to doesn't already exist the action will create it for you. Your workflow will also need to include the `actions/checkout@v1` step before this workflow runs in order for the deployment to work.

+#### Using a Container 📦
+
+If you use a [container](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/workflow-syntax-for-github-actions#jobsjob_idcontainer) in your workflow you may need to run an additional step to install `rsync` as this action depends on it. You can view an example of this below.
+
+```yml
+- name: Install rsync
+  run: |
+    apt-get update && apt-get install -y rsync
+    
+- name: Deploy
+  uses: JamesIves/github-pages-deploy-action@releases/v3
+```
+
 ## Configuration 📁
 
 The `with` portion of the workflow **must** be configured before the action will work. You can add these in the `with` section found in the examples above. Any `secrets` must be referenced using the bracket syntax and stored in the GitHub repositories `Settings/Secrets` menu. You can learn more about setting environment variables with GitHub actions [here](https://help.github.com/en/articles/workflow-syntax-for-github-actions#jobsjob_idstepsenv).

 ### Additional Build Files
 
 This action maintains the full Git history of the deployment branch. Therefore if you're using a custom domain and require a `CNAME` file, or if you require the use of a `.nojekyll` file, you can safely commit these files directly into deployment branch without them being overridden after each deployment.
