It is a two step process:

1. Add a new entry in the mkdocs.yml file
2. Write the corresponding documentation file in the docs folder

Then, the docs will be built using Read the Docs.

Figure 1. Open Google Chrome developer tools. Click on Play > Play Computer and click on Create Game for command examples.

Figure 2. As chess moves are played, Stockfish's response is displayed on the Network > WS > Messages tab.

Also recently a TCP socket server has been implemented in the chesslablab/chess-server repo for testing purposes.

Figure 3. Run the cli/testing.php script.

Figure 4. Connect to the TCP server via telnet and run commands.

Happy learning!
