+## 📦 Dependency Management & Updates
+
+This project keeps *two* dependency files under version control:
+
+| File | Purpose | Edited by |
+|------|---------|-----------|
+| **`requirements.in`** | Short, human-readable list of *top-level* libraries (no pins) | You |
+| **`requirements.txt`** | Fully-resolved, **pinned** lock file—including hashes—for exact, reproducible builds | `pip-compile` |
+
+### 🔧 Installing `pip-tools`
+
+```bash
+python -m pip install --upgrade pip-tools
+````
+
+### ➕ Adding / Updating a Package
+
+1. **Edit `requirements.in`**
+
+   ```diff
+   - sentence-transformers
+   + sentence-transformers>=4.1
+   + llama-index
+   ```
+2. **Re-lock** the environment
+
+   ```bash
+   pip-compile --upgrade
+   ```
+3. **Synchronise** your virtual-env
+
+   ```bash
+   pip-sync
+   ```
