Where to start with Thor?

So, yesterday i went to Forbidden Planet in Edinburgh and the guy was etremely helpful. I came away with Dare Devil vol 1, Cap. America Vol 1 and Hawkeye: My life as a weapon vol 1.

i should mention ive only just started reading, and so far, i 사랑 it!

However im really interested in 읽기 some Thor and Avngers Assemble, however i have no idea where to start 또는 which comic book to get first. Help?!?!?!

Thanks :D
