+---
+
+# TCR Setup
+
+Set up TCR (Test && Commit || Revert) for practicing baby-step programming.
+
+## Steps
+
+1. Ensure git is initialized:
+```bash
+git init
+```
+
+2. Create a TCR script:
+```bash
+cat > tcr.sh << 'EOF'
+#!/bin/bash
+# TCR: Test && Commit || Revert
+
+# Replace with your actual test command
+TEST_CMD="go test -v ./... || npm test"
+
+echo "Running TCR..."
+if $TEST_CMD; then
+    git add -A
+    git commit -m "TCR $(date +%H:%M:%S)"
+    echo "✅ Tests passed - Changes committed"
+else
+    git restore .
+    echo "❌ Tests failed - Changes reverted"
+fi
+EOF
+
+chmod +x tcr.sh
+```
+
+3. Test it:
+```bash
+./tcr.sh
+```
+
+## Usage
+
+After making a tiny code change:
+```bash
+./tcr.sh
+```
+
+- If tests pass → Changes automatically committed
+- If tests fail → Changes automatically reverted
+
+## Tips
+
+- Start with refactoring only (not new features)
+- Make the smallest possible changes
+- When you get stuck (keep reverting), take a break
+- Don't cheat with CTRL+Z to recover reverted code
+
+## Advanced: Watch Mode
+
+Auto-run TCR on file changes:
+```bash
+# macOS with fswatch
+fswatch -o src/ test/ | xargs -n1 -I{} ./tcr.sh
+
+# Linux with inotifywait
+while inotifywait -r -e modify src/ test/; do ./tcr.sh; done
+```
+
+Ask which test command to use, then create the TCR script and explain how to use it.
