 -----------
 SnapDump is available as docker application for easy deployment. Let's pull a stable version of the SnapDump server (check DockerHub to be up to date):
 
-    $ docker pull zweidenker/snap-dump:0.5.1.1
+    $ docker pull zweidenker/snap-dump:0.7
 
 To keep the snapshots on server restart we need to create a volume where snapshots can be stored. You do this by invoking:
 
     $ docker volume create SnapDump
 
 SnapDump uses internally the port 5555 for the server. This can be mapped to a local port on the host by specifying on the docker commandline. To start the server with that port and the former created volume invoke:
 
-    $ docker run -p 8888:5555 -v SnapDump:/snapshots zweidenker/snap-dump:0.5.1.1
+    $ docker run -p 8888:5555 -v SnapDump:/snapshots zweidenker/snap-dump:0.7
 
 Now our SnapDump server is up and running, we would like to first: report exceptions from a SnapDump handler image , and second: retrieve our reported exceptions on a SnapDump client image.
