They'll start with the time stone, which they'll get from strange after he sees the one timeline they win.
Then they'll jump back a bit more, and get the soul gem. When they find out the cost, nebula will give herself up to create it, and save gamora.
Then jump back some more and get the reality gem right after it's delivered to the collector.
Then another jump, to xandar to get the power stone
Finally they'll have to go to avengers 1 time to get the tesseract and the mind stone
Again, though, the mind stone becomes a big deal because they realize how much that'll change everything.
But, thanos catches on and starts persuing them through time.
They can't get the mind stone, and are forced back to the present for a fight.
But now there are 11 stones.
Avengers use the stones to slowly wear down thanos. He's not lost, but he's losing the will to fight. He noticed how far the avengers advanced, due to adversity, and realizes he may have been wrong, and that the right people make the right sacrifices for the right reasons.
He fends them off, goes to snap, everyone freaks .
Then everyone returns that was snapped.
Thanos decides to let people take the chance on solving the problem themselves. He leaves the gauntlet, avengers send the other gems back so as not to upset the timeline.
