Documentation Update #1522
Description
I downloaded latest version and tried to switch between modes as it told in the https://github.com/Azure/azure-powershell#2-modes but it seems the latest verion (and the versions later than 1.0.0) has no this option, instead of [Verb]-AzureRm[Noun] option is intoduced, i think it will be good to update the readme
