+# Test Automation Setup
+
+This directory contains pre-commit hooks for automated testing.
+
+## Installation
+
+Enable these hooks with:
+
+```powershell
+git config core.hooksPath .githooks
+```
+
+## Available Hooks
+
+### pre-commit (bash)
+Runs fast unit tests before allowing commits. Use on Linux/Mac or Windows with Git Bash.
+
+### pre-commit.ps1 (PowerShell)
+PowerShell version for Windows users. Configure with:
+
+```powershell
+# Add to .git/config or run:
+git config core.hooksPath .githooks
+```
+
+## Bypass (emergency only)
+
+```bash
+git commit --no-verify
+```
+
+## What Gets Tested
+
+Pre-commit runs:
+- Unit tests only (fast, < 30s)
+- Excludes slow/integration tests
+- Excludes Azure-dependent tests
+
+For full testing:
+```bash
+python scripts/test_runner.py --all --coverage
+```
