 * You can also import WRF from Github into a new empty Gitlab project on [Phaidra](https://gitlab.phaidra.org/explore). To get access to Gitlab, look at the [ZID guidlines](https://zid.univie.ac.at/gitlab/) and send a request via email to `support.phaidra@univie.ac.at`. Once you have access credentials, click on "New Project", then "Import Project", then "Repository by URL". This method might be advisable if you want to use Gitlab for tracking your own changes to the WRF code, but do not want to rely on the official repository.

 For other test cases, compilation might create a `run_me_first.csh` script in the same directory as the executables. If there is one, run it only once, before any other program. It will link any necessary lookup tables needed for the simulation (land-use, parameterizations, etc.).
