+# Git Hooks
+
+This directory contains Git hooks for the ExecuTorch repository.
+
+## Pre-commit Hook
+
+The pre-commit hook automatically updates the PyTorch commit pin in `.ci/docker/ci_commit_pins/pytorch.txt` whenever `torch_pin.py` is modified.
+
+### How It Works
+
+1. When you commit changes to `torch_pin.py`, the hook detects the change
+2. It parses the `NIGHTLY_VERSION` field (e.g., `dev20251004`)
+3. Converts it to a date string (e.g., `2025-10-04`)
+4. Fetches the corresponding commit hash from the PyTorch nightly branch at https://github.com/pytorch/pytorch/tree/nightly
+5. Updates `.ci/docker/ci_commit_pins/pytorch.txt` with the new commit hash
+6. Automatically stages the updated file for commit
+
+### Installation
+
+To install the Git hooks, run:
+
+```bash
+.githooks/install.sh
+```
+
+This will copy the pre-commit hook to `.git/hooks/` and make it executable.
+
+### Manual Usage
+
+You can also run the update script manually at any time:
+
+```bash
+python .github/scripts/update_pytorch_pin.py
+```
+
+### Uninstalling
+
+To remove the pre-commit hook:
+
+```bash
+rm .git/hooks/pre-commit
+```
+
+## Troubleshooting
+
+If the hook fails during a commit:
+
+1. Check that Python 3 is available in your PATH
+2. Ensure you have internet connectivity to fetch commits from GitHub
+3. Verify that the `NIGHTLY_VERSION` in `torch_pin.py` is in the correct format (`devYYYYMMDD`)
+4. Make sure the corresponding nightly release exists in the PyTorch nightly branch
+
+You can run the script manually to see detailed error messages:
+
+```bash
+python .github/scripts/update_pytorch_pin.py
+```
