+.SYNOPSIS
+The script is to generate service level readme if it is missing. 
+For exist ones, we do 2 things here:
+1. Generate the client but not import to the existing service level readme.
+2. Update the metadata of service level readme
+
+.DESCRIPTION
+Given a doc repo location, and the credential for fetching the ms.author. 
+Generate missing service level readme and updating metadata of the existing ones.
+
+.PARAMETER DocRepoLocation
+Location of the documentation repo. This repo may be sparsely checked out
+depending on the requirements for the domain
+
+.PARAMETER TenantId
+The aad tenant id/object id for ms.author.
+
+.PARAMETER ClientId
+The add client id/application id for ms.author.
+
+.PARAMETER ClientSecret
+The client secret of add app for ms.author.
