+# Git Hooks
+
+This directory contains global git hooks that can be used across all repositories.
+
+## Setup
+
+1. Configure git to use this directory for hooks:
+```bash
+git config --global core.hooksPath ~/dotfiles/git/hooks
+```
+
+2. Make hooks executable:
+```bash
+chmod +x ~/dotfiles/git/hooks/*
+```
+
+## Available Hooks
+
+- `pre-commit`: Run before each commit
+- `commit-msg`: Validate commit messages
+- `pre-push`: Run before pushing
+
+## Per-Repository Hooks
+
+To use repository-specific hooks instead of global ones:
+```bash
+git config --local core.hooksPath .git/hooks
+```
