I have updated as requested my section 00d5ab8
I have also proposed a more general overall in the general direction of the comments : e7045a8

• uniform use of sh/bash in the code blocks
• More uniform level heading (top level for provider, installation/usage for all templates)

I can revert the last commit if the change is an issue, one thing I didn't know how to do with mkdocs is to limit the TOC to level 3, as it is a bit to busy right now
