First, install Yeoman and generator-np-stack (we assume you have pre-installed node.js):
npm install -g yo
npm install -g noprotocol/generator-np-stack
Then generate your new project:
yo np-stack
Give your project a sensible name, and choose your desired Stack.
If you want to contribute to the generator the best thing to do is to follow these steps:
npm uninstall -g generator-np-stack
git clone git@github.com:noprotocol/generator-np-stack.git
cd generator-np-stack
npm link
This way you can work locally on the generator, and test your changes by running the yo
command as usual.
