 # Docker
 
+Docker is a containerization software.
+
 ## Description
 
+* You cannot use Docker in the cluster (the engine is not installed there and requires root privileges).
+
+* But you can use Docker to create your custom containers locally.
+
+## Create Docker containers
+
+Internally we have this GitHub repository with the receipes for many of the custom containers that we are generating and
+ hosting in our dockerhub.
+
+If you need/want to create a new container, you can follow guidelines on how is the most appropriate way of doing it,
+ and once you have a working version of it, you must:
+
+* Add your Dockerfile and associated files required for generating the container to our
+ [GitHub repository of containers](https://github.com/bbglab/containers-recipes). Make sure that your container is fully
+  reproducible.
+
+* If appropriate ask some BBG member with permission to upload it to the lab
+ [docker hub](https://hub.docker.com/u/bbglab).
+
+## Licensing (Docker Engine vs Docker Desktop)
+
+The *Docker Engine* (the runtime/daemon `dockerd` and related components) is open source and distributed under the
+ **Apache License 2.0** (a permissive license). Docker explicitly documents this in the Docker Engine manual:
+
+* Docker Engine licensing:
+ [https://docs.docker.com/engine/#licensing](https://docs.docker.com/engine/#licensing)
+* Docker Engine upstream license (Moby project):
+ [https://github.com/moby/moby/blob/master/LICENSE](https://github.com/moby/moby/blob/master/LICENSE)
+
+Note: Docker Desktop is a separate product with its own subscription/license terms; the Docker Desktop is licensed under
+ the
+ [Docker Subscription Service Agreement overview](https://www.docker.com/legal/docker-subscription-service-agreement/).
+  Docker also notes that the licensing terms for the Docker/Moby open-source projects (such as Docker Engine) aren’t
+   changing:
+
+* Docker Desktop license agreement note:
+ [https://docs.docker.com/subscription/desktop-license/](https://docs.docker.com/subscription/desktop-license/)
