Step 2 is not clear enough for beginners

[mattou07]

In the readme its not fully clear what this means exactly for a uSync beginner:

• Put an Old uSync v7 folder somewhere in your shiny new uSync Folder

Do I need to install the core uSync package (https://www.nuget.org/packages/uSync) in this case 8.11.3 for v8 or 4.0.16 for v7? Do I then run an uSync export which then populates a Usync folder on disk?

Happy to send over a PR to update the README, let me know if I have got anything wrong.

The Usync command returns with a 401 error for me: dotnet add package uSync.Migrations --prerelease

I was able to get around this by using the following command from nuget

dotnet add package uSync.Migrations --version 4.0.0-beta013
