Old two prong outlet was removed, the purpose of this photo is to show that there is no ground wire.
Then clean out the box.
Add ground wire, with green screw. Apparently everything is color coded.
Secure new outlet. Yes, it is upsided-down on purpose, for things that have the third prong it helps them stay in better as the ground pole is the longest, also if something spills the "bottom" which is our top, protrudes the farthest and will prevent the spill from getting in the outlet.
