 ### Command-Line Tool
 
-`gc-meox-tms` can be used as a command line tool in a Python console/Python scripts. To use the tool via the command line
-you will need one or more `txt` files with chemical compounds represented as SMILES (one SMILES per line). The tool can
-output results in flat `txt` format (one compound per line) or tab separated `tsv` format (all derivatives of a given molecule per line).
