1. Fork this repository to your own GitHub account and then clone it to your local device.
2. Install the dependencies: npm install.
3. Run npm link to link the local repo to NPM.
4. Then npm link this repo inside any nuxt example app with npm link nuxt.
5. Run npm run build or npm run dev inside your example app, if you created it with nuxt starter template.
6. Then you can run your example app with the local version of Nuxt.js (You may need to re-run the example app as you change server side code in the Nuxt.js repository).

Note that both npm and yarn has been seen to miss installing dependencies. To remedy that, you can either delete the node_modules folder in your example app and install again or do a local install of the missing dependencies.

Make sure to add tests into test/ directory and try them with npm test before making a pull request.
