Somehow I got involved in Microsoft Power BI. So I needed to do some quick catching up and as such I searched the internet for more information about that same topic.
And this is what I found (legal sources that is):
Microsoft Virtual Academy: https://mva.microsoft.com/search/SearchResults.aspx#!q=power%20bi&index=2&lang=1033
So these sources are a great way to get started right away. Enjoy!
