We are launching an official repository for the Azure SQL MI scripts, which will serve as a principal source location for the tools and scripts that we shall be publishing - https://github.com/Azure/sqlmi.
This GitHub repository is initially populated with the first folder and just 1 file, containing all SQLMI how-to series scripts, but we shall be expanding that folder in the nearest future with individual sections, and there are more exciting projects and tools that will be landing in the repository soon.
Regarding the SQL MI How-to series, we would like to remind that you can find the whole series with the following link http://aka.ms/sqlmi-howto where besides the scripts you will find the screenshots of the sample results and the detailed explanations.
