How these notes work
Written from real work. Every tip comes from production farms, tenants and cloud estates, not from a lab.
Safe by default. Reports are read-only. Anything that changes data supports -WhatIf, so you can see what it would do before it does it.
Consistent examples. Each topic uses fixed example names and URLs, such as sharepoint.ravindran.in, rg-notes-test, aws.ravindran.in or prj-notes-test, so you know exactly what to replace.
