+
+```bash
+git undo version        # Standard version command
+git undo self version   # The same (just a consistent way for other `git undo self` commands)
+```
+
+The version detection works in the following priority:
+1. Git tag version (if in a git repository with tags)
+2. Build-time version (set during compilation)
+3. "unknown" (fallback)
+
+### Self-Management Commands
+
+Update git-undo to the latest version:
+

+git undo self update

+

+```bash
+git undo self uninstall

+### Building with Version Information
+
+To build git-undo with a specific version:
+
+```bash
+# Using git describe
+VERSION=$(git describe --tags --always 2>/dev/null || echo "dev")
+go build -ldflags "-X main.version=$VERSION" ./cmd/git-undo
+
+# Or manually specify version
+go build -ldflags "-X main.version=v1.2.3" ./cmd/git-undo
+```
+
+### Testing
+
+Run the test suite:
+
+```bash
+go test ./...
+```
