-To run the image execute the following command:
+You need a local directory where you want to store the git repository.
+In the example below `mkdir /store/repo`.
+Make sure the quit process in the docker container has write access to this directory by executing:
+```
+sudo chown 1000 /store/repo
+sudo chmod u+w /store/repo
+```
+To run the image execute the following command (maybe you have to replace `docker` with `sudo docker`):
 
 ```
-docker run --name containername -v /existing/store/repo:/data aksw/quitstore
+docker run -it --name containername -p 8080:8080 -v /store/repo:/data aksw/quitstore
 ```
 
-The following example will map the quit store port to the host port 80.
+The following example will start the quit store in the background in the detached mode.
 
 ```
-docker run --name containername -p 80:8080 -v /existing/store.repo:/data aksw/quitstore
+docker run -d --name containername -p 8080:8080 -v /store/repo:/data aksw/quitstore
 ```
 
+Now you should be able to access the quit web interface under `http://localhost:8080` and the SPARQL 1.1 interface under `http://localhost:8080/sparql`.
