+## Use the Docker Image from the GitHub Container Registry
+
+This repository provides a Docker image hosted in the GitHub Container Registry (GHCR) that can be used to run the application easily. Below are the steps to pull and run the Docker image.
+
+1. **Pull the Docker Image from the GitHub Container Registry**
+
+```bash
+docker pull ghcr.io/swisstopo/swissgeol-boreholes-dataextraction-api:edge
+```
+
+1. a. **Run the docker image from the Terminal**
+
+```bash
+docker run -d --name swissgeol-boreholes-dataextraction-api -e AWS_ACCESS_KEY_ID=XXX -e AWS_SECRET_ACCESS_KEY=YYY -e AWS_ENDPOINT=ZZZ -p 8000:8000 ghcr.io/swisstopo/swissgeol-boreholes-dataextraction-api:TAG
+```
+
+Adjust the port mapping (8000:8000) based on the app's requirements.
+
+NOTE: Do not forget to specify your AWS Credentials.
+
+1. b. **Run the docker image from the Docker Desktop App**
+
+Open the Docker Desktop app and navigate to `Images`, you should be able to see the image you just pulled from GHCR. Click on the image and click on the `Run` button on the top right of the screen. 
+
+![](assets/img/docker-1.png){ width=400px }
+
+Then open the `Optional Settings` menu and specify the port and the AWS credentials
+
+![](assets/img/docker-2.png){ width=800px }
+
+
+2.  **Verify the Container is Running**
+
+To check if the container is running, use:
+
+```bash
+docker ps
+```
