-However, please remember that such luxury is limitted:
-> Gitpod offers a free plan for new users which includes 50 hours of standard workspace usage.
->If you need more hours, you can upgrade to one of the paid plans in your personal settings.

 After each pipeline run the main output directory will contain three subdirectories: `configfiles`, `simulations` and `logs`. Each simulation run with a specific set of parameters is encoded by a 4-letter code. The first directory contains configuration files for each of the simulation runs; `simulations` contain all _demon_ output files; `logs` keep captured standard output and error streams for the commands.
 
-## Example
-
-Feel free to run the pipeline and inspect the results yourself in an [interactive jupyter notebook](https://mybinder.org/v2/gh/AngryMaciek/warlock/master?labpath=notebook.ipynb) we prepared.  
-Alternatively, feel free to run a small test script on your local machine with
-`bash testscript.sh`.
