Here's how to compile Pattern Monster (requires npm)

[LinuxBeaver]

Download from Github then go into the main folder and input
npm install && npm run build

then input node sapper/build to active port 3000. Then in your web browser go to http://localhost:3000/

Every time you run pattern monster you will need to run node sapper/build first, so you might want to consider making a bash script that does it on startup on your system.
