What Happened in Libya During the Civil War and NATO Interference?

Any Libya experts in here? I saw this comment on reddit between someone saying Obama wasn't perfect because he helped bomb Libya, which is obviously not in a great state right now, and this person - but it doesn't seem like the whole story to me. But all the sources I can find online are Western ones just saying the no-fly zone was instituted because he bombed his own civilians and helped terrorists or something.

if you’re going to lie, at least make it believable. Libya had a civil war during the Arab spring in 2011. while other countries modernized, gaddafi responded by bombing and levelling his own capital city. Obama and the EU helped by no fly zone over Tripoli to stop gaddafis war planes bombing his own people.

this was only 12 years ago, blaming Obama for the Arab spring which took place in 19 Arab countries is downright idiotic.

This doesn't make sense to me. Why would he do that? Also, what's the causes for the civil war? What are the sides? This person doesn't explain that and it makes me think there's something key missing.
