 ### Docker execution
+If you don't want to use the JAR directly, you may run the project using a [Docker container](https://www.docker.com/). First you will need to download or build the image, and then run it.
 
-First build the image using the `Dockerfile` in project folder:
+#### Reusing a pre-existing image
+We build containers in the [GitHub image registry](https://github.com/dgarijo/Widoco/pkgs/container/widoco) for all latest releases. In order to import one, just run the following command, stating the version of Widoco you prefer (e.g., for v1.4.23):
+
+```
+docker pull ghcr.io/dgarijo/widoco:v1.4.23
+```
+
+To browse all available images, see the [GitHub image registry](https://github.com/dgarijo/Widoco/pkgs/container/widoco).
+
+#### Building the image yourself
+
+Build the image using the `Dockerfile` in project folder:
 
 ```bash
 docker build -t dgarijo/widoco .
 ```
 
+#### Running WIDOCO's image
+
 You can now execute WIDOCO through the command line. Usage:
 
 ```bash
 docker run -ti --rm dgarijo/widoco [OPTIONS]
 ```
 
+**Note:** If you downloaded the image from the GitHub registry, you will have to change `dgarijo/widoco` with the name of the image you downloaded. For example `ghcr.io/dgarijo/widoco:v1.4.23`.
+
 If you want to share data between the Docker Container and your Host, for instance to load a local ontology file (from PATH), you will need to mount the container
 with host directories. For instance:
