Suggestions

I am not absolutely sure how to do block quotations either but I think it can be done using colons, so for each line of your quote you would place a colon then indent as much as you want using your space bar (tab bar doesn't work).

First line of quotation

Second line of quotation

What I did:

: (insert spaces) First line

: (insert spaces) Second line

You might find an easier way of doing it!
