Installing Modules in Homeassistant

Hey, i am new to home assistant and i wanted to create a responsive front end to use on pc as well as on my phone.

i have found a github repo which seems to be the exact thing i need:

However, since the documentation is very minimalistic, i just cannot figure out how to install this.
Can somebody help me out?

I think ā€œInstall threshold-stack.js as a moduleā€ is referring to Settings | Dashboards.

If you click on the three dots top right you get a list of dashboard resources, with button allowing you to add another one.

Yes, that worked thank you!!

For everybody else that might need this:
I put the file in this path:
/homeassistant/www/community/threshold-stack/threshold-stack.js

For some reason i dont know, you have to change ā€œ/homeassistant/wwwā€ to ā€œ/localā€ when adding the resource to the dashboard (while keeping the file in the same place!!!)
/local/community/threshold-stack/threshold-stack.js
