+
+1. You can deploy the front end using skaffold
+
+   ```
+   skaffold dev --cleanup=False
+   ```
+
+   * Your Kubernetes context should be set to using the `github-probots-dev` namespace
+   * This will continually rebuild and upate your code
+   * Skaffold's file sync feature is used to update the code in the image without rebuilding and
+     redeploying
+   * This makes redeploying very easy.
+
+1. To send a GitHub webhook event you can either open up an issue or you can use `scripts/send_request.py`
+
+   * The latter is useful because it avoids needing to open up a new GitHub issue
+
+     * Right now the bot is only designed to respond to issues opened events.
