file: # Getting Started With Schematics
  
  This repository is a basic Schematic implementation that serves as a starting point to create and publish Schematics to NPM.
  
  ### Testing
  
  To test locally, install `@angular-devkit/schematics-cli` globally and use the `schematics` command line tool. That tool acts the same as the `generate` command of the Angular CLI, but also has a debug mode.
  
  Check the documentation with
  ```bash
  schematics --help
  ```
  
  ### Unit Testing
  
  `npm run test` will run the unit tests, using Jasmine as a runner and test framework.
  
  ### Publishing
  
  To publish, simply do:
  
  ```bash
  npm run build
  npm publish
  ```
  
  That's it!
