-The package requires the Python package [pygmx](https://github.com/mdevaluate/pygmx),
-which handles reading of Gromacs file formats.
-Installation of pygmx is described in its own repository.
 
 The mdevaluate package itself is plain Python code and, hence, can be imported from its directory directly,

 ## Running the tests
 
 Mdevaluate includes a test suite that can be used to check if the installation was succesful.
