+- From the repo, install `emoji_paint.py` on your Pico. In the repo, it can be found under the pico/ folder
+- In Thonny, run the file on the Pico, and get the IP address from the console
+- If it does not run, or you do not see the IP address, then setup `WIFI_CONFIG.py` or install required libraries and try again.

+- If you have multiple Cosmic Unicorns, you can add multiple entries to control them all. Make sure to add commas in the right spots so the file is valid JSON format. You may want to install the user interface only on one of the Picos, and install server files only on the others. It's up to you.
