 Ribasim is typically used as a command-line interface (CLI). It is distributed as a `.zip`
 archive, that must be downloaded and unpacked. It can be placed anywhere, however it is
 important that the contents of the zip file are kept together in a directory. The Ribasim
 executable is in the main folder.
 
-To check whether the installation was performed successfully, open a terminal and go to the path where the executable is for example 'C:\Ribasim\ribasim_windows'.

+- Ribasim executable - Linux: [ribasim_linux.zip](https://github.com/Deltares/Ribasim/releases/latest/download/ribasim_linux.zip)
