+## Example run
+
+The following shows a simple example of how to run the example
+application. First,the container is started, then the backend is startend in the background inside the container, and finally the CLI is started in the foreground.
+
+```
+  $ sudo docker run --name clixon --rm -td clixon/clixon
+  $ sudo docker exec -it clixon clixon_backend -s init -f /usr/local/etc/example.xml
+  $ sudo docker exec -it clixon clixon_cli -f /usr/local/etc/example.xml
+  > set interfaces interface e
+  > show configuration 
+  interfaces {
+    interface {
+        name e;
+        enabled true;
+    }
+  }
+  > q
+  $ sudo docker kill clixon
+```
+
+Note that this is a special case since the example is
+already a part of the installation. If you want to add your own
+application, such as plugins, cli syntax files, yang models, etc, you
+need to extend the base container with your own additions.
