Kusto Query Internals - Azure Sentinel Reference

@DebugPrivilege posted some useful docs here;

Folks, who are into Azure Sentinel. I have released a documentation, where I cover different basic concepts of KQL. It contains 9 chapters with different use-cases, and it walks you through different steps to create a KQL query for the described use-case. https://t.co/CtbVIBJZXz
