+# This image belongs to a larger project called Bioinformatics Docker Images Project (http://pegi3s.github.io/dockerfiles)
+## (Please note that the original software licenses still apply)
+
+This image facilitates the usage of docker-manager, a program with a graphical interface for managing Docker images.
+
+# Using the docker-manager image in Linux
+You should run the following command: `docker run --rm -ti -e USERID=$UID -e USER=$USER -e DISPLAY=$DISPLAY -v /var/db:/var/db:Z -v /tmp/.X11-unix:/tmp/.X11-unix -v $HOME/.Xauthority:/home/developer/.Xauthority -v /var/run/docker.sock:/var/run/docker.sock -v /tmp:/tmp pegi3s/docker-manager`
+
+Because of its graphical interface you must run the `xhost +` command first.
