You should configure npm init defaults before using this package.

Run the following commands and replace the values below with your own:

npm config set init-author-email ""
npm config set init-author-name "Nick Baugh"
npm config set init-author-url ""
npm config set init-license "MIT"
npm config set init-version "0.0.0"

These defaults get utilized by lass when scaffolding a package and npm init in general.

To check your existing configuration, run npm config list -l.

Version Bump and Release

We highly recommend to use the tools np and release to version bump and release your package to GitHub and NPM.
