Microsoft Teams Free - feature overview

Dear community,

I'm looking for a Microsoft approved feature overview for Microsoft Teams Free. In the past there was one on https://www.google.be/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&uact=8&ved=2ahUKEwjcleHnrbroAhUE-aQKHdFADpgQFjACegQIDBAG&url=https%3A%2F%2Fproducts.office.com%2Fen-ie%2Fmicrosoft-teams%2Ffree&usg=AOvVaw12IMqF8FqfFDxmmShp6FPT but recently the content changed and the overview disappeared.

Can anyone help?
