 Place the executables into your ``$HOME/bin/`` directory or path. Place the `.XTBPARAM` folder and `.mass_raw.arg` file into your `$HOME` directory (these files can appear to be hidden). 
 To evaluate the results and create a spectrum, download and use the [PlotMS](https://github.com/qcxms/PlotMS) program. For visualization of the calculated spectra, we recommend the useage of the **xmgrace** program. Examples for an input file and coordinate file can found in the `EXAMPLES` file.
