+### Lockfile Installation
+PMG seamlessly protects lockfile-based installations:
+
+```bash
+npm install          # Uses package-lock.json
+pnpm install         # Uses pnpm-lock.yaml
+bun install          # Uses bun.lock
+
+pip install -r requirements.txt   # Uses requirements file
+```
+
+PMG scans the exact package versions specified in lockfiles and blocks installation if malicious packages are detected.
