@@ -21,3 +21,59 @@ To run the Docker container from the image, use the following command:
 ```bash
 docker run -d -p 8000:8000 safeqr-fastapi-app
 ```
+
+This will start the FastAPI application in a Docker container, making it accessible at `http://localhost:8000`.
+
+## Stop/Kill the Docker Container
+
+To stop the running container, first, find the container ID:
+
+```bash
+docker ps
+```
+
+This command lists all running containers. Find the `CONTAINER ID` for `safeqr-fastapi-app`.
+
+To stop the container, use:
+
+```bash
+docker stop <container_id>
+```
+
+Replace `<container_id>` with the actual ID of your container.
+
+If you want to remove the container entirely after stopping it:
+
+```bash
+docker rm <container_id>
+```
+
+## Accessing the Application Logs
+
+If you need to view the logs of the running container, use:
+
+```bash
+docker logs <container_id>
+```
+
+## Removing the Docker Image
+
+If you need to remove the Docker image, use the following command:
+
+```bash
+docker rmi safeqr-fastapi-app
+```
+
+This will remove the Docker image from your local machine.
+
+## Troubleshooting
+
+- **Port Conflict**: If port 8000 is already in use, you can change the port mapping. For example, to map the container's port 8000 to port 8080 on your machine, use:
+
+  ```bash
+  docker run -d -p 8080:8000 safeqr-fastapi-app
+  ```
+
+- **Container Already Running**: If you get an error that the container is already running, stop the existing container as shown above.
