+# Server Example
+
+This is an example server based on [Santa Cat](https://santacat.ai). You can run the server with this command:
+
+```
+flask --app daily-bot-manager.py --debug run
+```
+
+Once the server is started, you can load `http://127.0.0.1:5000/spin-up-kitty` in a browser, and the server will do the following:
+
+- Create a new, randomly-named Daily room with `DAILY_API_KEY` from your .env file or environment
+- Start the `10-wake-word.py` example and connect it to that room
+- 301 redirect your browser to the room
