 ## 1. Small Scale Test Case
-Set up an ICON test case by cloning [`icon-nwp`](https://gitlab.dkrz.de/icon/icon-nwp) and integrate in the ICON testing infrastructure with a low number of grid points and a few time steps (about 6). Existing use cases like the [Aquaplanet](https://gitlab.dkrz.de/icon/icon-nwp/-/blob/master/run/exp.exclaim_ape_R02B04) one can serve as a template. Your test case should be saved as `run/exp.<experiment_name>`.

 The idea here is to test the code path of the final setup and identify potential issues coming from upstream source code.
