I wasn't sure if I need to install the stockfish engine separately because it looks to be included in the src. Also I know this is alpha so just was dropping a note if you haven't seen this yet :)

[PhilLecl]

Looks like the issue is that Stockfish isn't installed.
The stockfish directory in this repo includes stuff for building Stockfish using docker, but you'll still need to set it up manually. It's probably easiest for you to just install Stockfish yourself and try again.

[koskorya]

ahh yup installing Stockfish separately does the trick!

[Quintium]

@koskorya How did you install Stockfish? Does it just need to be downloaded or placed somewhere in the directory? Because I get a similar error even after downloading Stockfish.
