# Controls when the action will run. 
on:
  # Triggers the workflow on push or pull request events but only for the master branch
  push:
    branches: [ master ]
  pull_request:

  # Allows you to run this workflow manually from the Actions tab

# A workflow run is made up of one or more jobs that can run sequentially or in parallel

  # This workflow contains a single job called "build"

    # The type of runner that the job will run on
    runs-on: ubuntu-latest
