Hi!

From my perspective, every module (whether you house it on GitHub, an internal system, anywhere) should have a README.md to at the very least, provide:

• What is this
• Prerequisites
• How to install
• Example(s) of common scenario(s)

Also... less critical, but potentially helpful, you might consider some basic simple format folks can start from (perhaps including a common install/discovery snippet with Install-Module ModuleName, Get-Help about_ModuleName, Get-Command -Module ModuleName`, etc.

Cheers!
