Help you deploying your Sphinx documentation to Github Pages.

1. Set the publishing sources to "Github Actions"

2. Create workflow:

   name: Deploy Sphinx documentation to Pages
   
   # Runs on pushes targeting the default branch
   on:
     push:
       branches: [master]
   
   jobs:
     pages:
       runs-on: ubuntu-20.04
       environment:
         name: github-pages
         url: ${{ steps.deployment.outputs.page_url }}
       permissions:
         pages: write
         id-token: write
       steps:
       - id: deployment
         uses: sphinx-notes/pages@v3
