 ## Deploy
 
+### Pull from Github Repository
+
+This instance uses Docker Compose to deploy the application into the port 3015.

+2. Generate a new token (Classic)
+3. Ensure you check the permission "read:packages" and "No expiration".
+4. In the server, login into docker, introduce your username and the token generated:
+  ```bash
+  docker login ghcr.io --username github-username
+  ```
+5. You should stay logged permanently, you should not need to repeat this process.
