# How to install MSS for GNU Octave

The m-files of the MSS (Marine Systems Simulator) toolbox are compatible with MATLAB and the free software GNU Octave (https://www.octave.org), facilitating broad accessibility and application in marine systems simulation. To begin using the MSS toolbox, ensure it is installed and properly set up in your GNU Octave environment. 

## Download the MSS Directory:
