@israel05 Sure. Just navigate to the modules directory and git-clone the repository there.
cd modules
git clone https://github.com/rmrustem/MMM-quotes.git
Then you will need to add the module config to your config/config.js file like this:
modules: [
{
module: "alert",
},
{
module: 'MMM-quotes',
position: "middle_center",
},
...
]
