-# Git hooks for Godot Engine
-
-This folder contains Git hooks meant to be installed locally by Godot Engine
-contributors to make sure they comply with our requirements.
-
-## List of hooks
-
- Pre-commit hook for `clang-format`: Applies `clang-format` to the staged
-  files before accepting a commit; blocks the commit and generates a patch if
-  the style is not respected.
-  You may need to edit the file if your `clang-format` binary is not in the
-  `PATH`, or if you want to enable colored output with `pygmentize`.
- Pre-commit hook for `black`: Applies `black` to the staged Python files
-  before accepting a commit.
- Pre-commit hook for `make_rst`: Checks the class reference syntax using
-  `make_rst.py`.
-
-## Installation
-
-Copy all the files from this folder into your `.git/hooks` folder, and make
-sure the hooks and helper scripts are executable.
-
-#### Linux/MacOS
-
-The hooks rely on bash scripts and tools which should be in the system `PATH`,
-so they should work out of the box on Linux/macOS.
-
-#### Windows
-
-##### clang-format
- Download LLVM for Windows (version 13 or later) from
-  <https://releases.llvm.org/download.html>
- Make sure LLVM is added to the `PATH` during installation
-
-##### black
- Python installation: make sure Python is added to the `PATH`
- Install `black` - in any console: `pip3 install black`
