 3. **Start the Lab:**
    - Navigate to the project directory.
-   - Run `containerlab deploy -t lab_vxlan.yml` to deploy the lab topology.
+   - Run `sudo containerlab deploy -t lab_vxlan.yml` to deploy the lab topology.
 
 ## Usage
 
 - Once the lab is deployed, you can access the individual nodes (spines and leaves) via CLI or SSH to configure and test VXLAN-EVPN functionalities.
 - Use the `hosts` directory to modify or apply specific configurations.
