I would like to create a really simple Single Page Application on Azure.

I have cloned https://github.com/staticwebdev/vanilla-basic

It has lots of folders and files which are very foreign to me (eg .devcontainer, .github/workflows, tests, playwright, typescript files)

I do not use Visual Studio Code Editor and do not want anything installed except for what is required for a site to run on Azure.

What is the absolute minimum that can be in a GitHub repo for it to work with Azure 'Static Web Apps'?

This is what the current default repo contents are:

.devcontainer
.github/workflows
src
tests
.gitignore
package-lock.json
package.json
playwright.config.ts
readme.md

Ideally, I would just like it to contain:

/js
/css
index.html

(It would be great if a tutorial existed which demonstrated how to create such a simple repo for Azure, I can't find one).
