-Patch for the MC/DC checker
----------------------------
-
-Currently the MC/DC checker works for simple C programs but crashes when run against code in several ROS packages. A `patch <https://gist.githubusercontent.com/iche033/ef0d23c85f4d810fa26c722027894c91/raw/f0a9f48abffff0101b9e7f2a2fd94f79cafe360e/mcdc_checker.patch>`_ with minor code changes to checker code is needed to avoid the crash. See instructions below for applying the patch to the checker.

 How to run the MC/DC checker
 -----------------------------
 
-The recommended way of running the check is to use the upstream docker image as it requires a patched version of ``libclang``.

-.. code-block:: bash
-
-   docker cp mcdc_checker.py `docker ps | grep mcdc-checker | awk '{print $1;}'`:/app/src/mcdc_checker.py

-Go back to the docker container and run the ``mcdc_checker`` cmd

-.. code-block:: bash
-
-   mcdc_checker -a
+   docker run -it -v $(pwd):/code registry.gitlab.com/gtd-gmbh/mcdc-checker/mcdc-checker -a
 
 The ``-a`` flag tells the check to run recursively on all files in this directory. You should see the script start processing the source code and generating output. See notes below for more info about possible error messages.
