 ## Builds and publishing to Docker Hub
 
-Docker images are built:
+Docker images can be built and published in two ways:
 
-- when a new commit is done to the master branch. This triggers build and updated of the published genode/{image}:latest
-- when a new release is pusblished. Tagging follows the {image}_{tag}, and a new geonode/{image}:{tag} is published.
+- When a new release is pusblished. Tagging follows the {image}#{tag}, and a new geonode/{image}:{tag} is published.
+- Using the manual action workflow
 
 Example:
- - A new commit changes a file under the `docker/geoserver` folder -> `geonode/geoserver:latest` is built and published to Docker Hub
- - A release is done with the tag `postgis_15.1` -> `geonode/postgis:15.1` is built and published to Docker Hub
+ - A release is done with the tag `geoserver#2.23.3-v2` -> `geonode/geooserver:2.23.3-v2` is built and published to Docker Hub
