How to use external engines on Lichess!

Long story short

Here are the steps you have to follow:

• Go to fitztrev's lichess-tauri (Lichess Local Engine) GitHub project, to Releases
• Download the newest version of the app (at the moment of writing version 0.0.5) for your operating system
• Run the installer and run the application
• Log in to Lichess
• DO NOT click on the Install Stockfish 16 button
• Download the version of Stockfish (or any other UCI-compatible engine) that works best on your machine
• Only then click on the *Or add your own engine * button
• Choose a descriptive title for the engine
• Click on the Select button in the Binary section
• Select the binary file for your preferred engine
• Now you can go to lichess.org and select whatever engine you configured in the Analysis/Study hamburger menu on the right side (bottom)
