The documentation now contains a description to reuse the initially create container. This way the user can start where they left off. The documentation only described creating a new container each and every time leaving users to create a new login each and every time.

 The easiest way to start WebGoat as a Docker container is to use the all-in-one docker container. This is a docker image that has WebGoat and WebWolf running inside.
 
 ```shell
-
 docker run -it -p 127.0.0.1:8080:8080 -p 127.0.0.1:9090:9090 -e TZ=Europe/Amsterdam webgoat/webgoat
 ```
 
+If you want to reuse the container, give it a name:
+
+```shell
+docker run --name webgoat -it -p 127.0.0.1:8080:8080 -p 127.0.0.1:9090:9090 -e TZ=Europe/Amsterdam webgoat/webgoat
+```
+
+As long as you don't remove the container you can use:
+
+```shell
+docker start webgoat
+```
+
+This way, you can start where you left off. If you remove the container, you need to use `docker run` again.
+
 **Important**: *Choose the correct timezone, so that the docker container and your host are in the same timezone. As it is important for the validity of JWT tokens used in certain exercises.*
