## Github repository
Create a new file in your repository `.github/workflows/on-main-push-deploy-do.yml` and add following:

```
name: Deploy to DigitalOcean Droplet
'on':
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Deploy to DigitalOcean Droplet

        with:
          host: ${{secrets.HOST}}
          username: ${{secrets.USERNAME}}
          key: ${{secrets.KEY}}
          script: |
            export NVM_DIR=~/.nvm
            source ~/.nvm/nvm.sh
            rm -rf test
            mkdir test
            cd test
            git clone git@github.com:username/projectname
