## Overview
|
|
|
|
[Stockfish][website-link] is a **free and strong UCI chess engine** derived from
|
|
Glaurung 2.1 that analyzes chess positions and computes the optimal moves.
|
|
|
|
Stockfish **does not include a graphical user interface** (GUI) that is required
|
|
to display a chessboard and to make it easy to input moves. These GUIs are
|
|
developed independently from Stockfish and are available online. **Read the
|
|
documentation for your GUI** of choice for information about how to use
|
|
Stockfish with it.
|
|
|
|
See also the Stockfish [documentation][wiki-usage-link] for further usage help.
|
|
|
|
## Files
|
|
|
|
This distribution of Stockfish consists of the following files:
|
|
|
|
* [README.md][readme-link], the file you are currently reading.
|
|
|
|
* [Copying.txt][license-link], a text file containing the GNU General Public
|
|
License version 3.
|
|
|
|
* [AUTHORS][authors-link], a text file with the list of authors for the project.
|
|
|
|
* [src][src-link], a subdirectory containing the full source code, including a
|
|
Makefile that can be used to compile Stockfish on Unix-like systems.
|
|
|
|
* a file with the .nnue extension, storing the neural network for the NNUE
|
|
evaluation. Binary distributions will have this file embedded.

### Donating hardware
|
|
|
|
Improving Stockfish requires a massive amount of testing. You can donate your
|
|
hardware resources by installing the [Fishtest Worker][worker-link] and viewing
|
|
the current tests on [Fishtest][fishtest-link].
|
|
|
|
### Improving the code
|
|
|
|
In the [chessprogramming wiki][programming-link], many techniques used in
|
|
Stockfish are explained with a lot of background information.
|
|
The [section on Stockfish][programmingsf-link] describes many features
|
|
and techniques used by Stockfish. However, it is generic rather than
|
|
focused on Stockfish's precise implementation.
|
|
|
|
The engine testing is done on [Fishtest][fishtest-link].
|
|
If you want to help improve Stockfish, please read this [guideline][guideline-link]
|
|
first, where the basics of Stockfish development are explained.
|
|
|
|
Discussions about Stockfish take place these days mainly in the Stockfish
|
|
[Discord server][discord-link]. This is also the best place to ask questions
|
|
about the codebase and how to improve it.
|
|
|
|
## Compiling Stockfish
|
|
|
|
Stockfish has support for 32 or 64-bit CPUs, certain hardware instructions,
|
|
big-endian machines such as Power PC, and other platforms.
|
|
|
|
On Unix-like systems, it should be easy to compile Stockfish directly from the
|
|
source code with the included Makefile in the folder `src`. In general, it is
|
|
recommended to run `make help` to see a list of make targets with corresponding
|
|
descriptions. An example suitable for most Intel and AMD chips:
|
|
|
|
```
|
|
cd src
|
|
make -j profile-build
|
|
```
|
|
|
|
Detailed compilation instructions for all platforms can be found in our
|
|
[documentation][wiki-compile-link]. Our wiki also has information about
|
|
the [UCI commands][wiki-uci-link] supported by Stockfish.
|
|
|
|
## Terms of use
|
|
|
|
Stockfish is free and distributed under the
|
|
[**GNU General Public License version 3**][license-link] (GPL v3). Essentially,
|
|
this means you are free to do almost exactly what you want with the program,
|
|
including distributing it among your friends, making it available for download
|
|
from your website, selling it (either by itself or as part of some bigger
|
|
software package), or using it as the starting point for a software project of
|
|
your own.
|
|
|
|
The only real limitation is that whenever you distribute Stockfish in some way,
|
|
you MUST always include the license and the full source code (or a pointer to
|
|
where the source code can be found) to generate the exact binary you are
|
|
distributing. If you make any changes to the source code, these changes must
|
|
also be made available under GPL v3.
