## The UCI protocol and available options
-The Universal Chess Interface (UCI) is a standard protocol used to communicate with a chess engine,
-and is the recommended way to do so for typical graphical user interfaces (GUI) or chess tools.

-For users, the following UCI options, which can typically be set via a GUI, are available in Stockfish:
+Developers can see the default values for UCI options available in Stockfish by typing
+`./stockfish uci` in a terminal, but the majority of users will typically see them and
+change them via a chess GUI. This is a list of available UCI options in Stockfish:
* #### Threads
The number of CPU threads used for searching a position. For best performance, set
For developers the following non-standard commands might be of interest, mainly useful for debugging:
- * #### bench ttSize threads limit fenFile limitType evalType
- Performs a standard benchmark using various options. The signature or standard node
- count is obtained using all defaults. `bench` is currently `bench 16 1 13 default depth mixed`.
