+# Git Hooks for Azure CLI Extension Development
+
+## Setup
+
+Please run the following command to enable the hooks.
+
+```bash
+azdev setup -c {azure_cli_repo_path} -r {azure_cli_extension_repo_path}
+
+# if you install azdev which version is less than 0.1.84, you need to run the following command to enable the hooks
+git config --local core.hooksPath .githooks
+```
+
+## Usage
+
+Every time you git commit or git push, please make sure you have activated the python environment and completed the azdev setup.
+
+If you want to skip the verification, you can add `--no-verify` to the git command.
+
+## Note
+
+### pre-commit
+
+The pre-commit hook (`pre-commit.ps1`) performs the following checks:
+
+1. Verifies that azdev is active in your current environment
+2. Runs `azdev scan` on all staged files to detect potential secrets
+3. If any secrets are detected, the commit will be blocked
+   - You can use `azdev mask` to remove secrets before committing
+   - Alternatively, use `git commit --no-verify` to bypass the check
+
+### pre-push
+
+The pre-push hooks (`pre-push.sh` for bash and `pre-push.ps1` for PowerShell) perform several quality checks:
+
+1. Verifies that azdev is active in your current environment
+2. Confirms azure-cli is installed in editable mode
+3. Checks if your branch needs rebasing against upstream/dev
+   - If rebasing is needed, displays instructions and provides a 5-second window to cancel
+4. Runs the following quality checks on changed files:
+   - `azdev lint`: Checks for linting issues
+   - `azdev style`: Verifies code style compliance
+   - `azdev test`: Runs tests for modified code
+5. If any check fails, the push will be blocked
+   - Use `git push --no-verify` to bypass these checks (not recommended)
+
+The hooks support both Windows (PowerShell) and Unix-like systems (Bash), automatically using the appropriate script for your environment.
