+1. Clone the recent version to your psono server into the folder (/usr/lib/check_mk/local/)
 2. Edit the Script and set the URL to yours.
-3. Copy the edited Script into the Check_MK folder `cp psono-healthcheck.py /usr/lib/check_mk_agent/local/`
-4. Set the execution permission `chmod +x /usr/lib/check_mk_agent/local/psono-healthcheck.py`
-5. Got to your Check_MK WATO and search for new services
-6. Finished - You should now have a working service named psono-health
+3. Set the execution permission `chmod +x /usr/lib/check_mk_agent/local/check-psono/psono-healthcheck.py`
+4. Create symbolic link to the python file `ln -s /usr/lib/check_mk/local/check-psono/psono-healthcheck.py /usr/lib/check_mk/local/psono-healthcheck.py`
+6. Go to your Check_MK WATO and search for new services
+7. Finished - You should now have a working service named psono-health
 
 ### Docker Checks
 To also Check the Docker Containers you need pip and the docker-py library installed.
-If you got that you can uncomment the import for docker and the for-loop.
+If you got that you can uncomment the Lines 4,5,7,9 and 10.
 Make shure the Containers you want to check are in the CONTAINER_NAMES list, remove if you don't have all of them on your server.
+Also male shure you synchronised the Submodule (`git submodule update --init --recursive`).
