(CNN)With both the NCAA men's and women's postseason basketball tournaments underway, here's what you need to know about the road to both Final Fours.
Thirty-two teams automatically qualify for the men's tournament after winning their respective conference tournaments. A selection committee determines which other teams will receive one of 36 at-large bids for a total of 68 teams.
This year's edition of the women's tournament will be the first to field 68 teams. The selection process is identical to the men's tournament with 32 automatic bids for winning a conference tournament and the remainder being at-large.
The Baylor Bears (men) and Stanford Cardinal (women) are the defending champions -- both will be back to make a run for a coveted repeat.

Filling out a bracket
Sometimes, there's no rhyme or reason on how to successfully fill out and produce a "winning" March Madness bracket.
If you're a college basketball expert, great. If you're not, picking winners based on school names or mascots works fine too.
The excitement lies in how many games correctly predicted before your bracket "busts."
Five names to watch
Otherwise known as "Coach K," Duke's head coach is a five-time national champion who's also taken the Blue Devils to the Final Four 12 different times.
Coach K, 75, is stepping down from his post at the conclusion of the NCAA men's basketball tournament.
You can bet tears will flow as the all-time winningest coach in men's Division I college basketball walks off the court for the final time.
