The way to install Project Lima to your new project is to download from NPM. This will put Project Lima as a module in your node_modules folder in which you can include JS and SCSS files into your build process.
There are two ways of downloading from NPM:
In your command line programme, when you are pointed at the route of your project, type:
npm i ecce-lima. To save to your package.json file add this to the end of that statement
In your package.json file, in the devDependencies object, add
"ecce-lima": "latest", (if you need a specific version, replace the word latest with that version number). Now when you run
npm i it will install Project Lima with the rest of your packages.
