This is my personal website template for Assemble. I've tried to take the best parts from html5bp, bootstrap and many others.
You should have a couple of things installed on your system, please check the instructions on how to do that.
After you're done with those, just clone the repository to a folder you want:
git clone https://github.com/Arkkimaagi/assemble-website-template website-template
Then go to the directory and install all the npm packages required:
cd website-template
npm i
Now you're ready to run the build script:
grunt
That should run the template generation and you should see it process a bunch of files.
You can now type grunt --help
and see what options you have, or you can take a peak at Gruntfile.js that sets it up.
