Adapting Recipes for Instant Pot

I just got an Instant Pot and am already in love. Would love to start using it to cook chili. My go-to recipe is the ATK vegetarian chili recipe (http://www.familycookbookproject.com/...), which calls for 10 minutes of browning of onions (can do on sauté function), then 45 minutes of oven-cooking with beans at 300 degrees, then adding in tomato and bulgur and cooking an additional 2 hours.

So, any thoughts on how to adapt for making in the Instant Pot? I can't see any reason why it wouldn't work, and I know chili is a common pressure cooker meal. I could also do it in the slow cooker function if there's any thoughts that that would be better, but my feeling so far is that the pressure cooker seems to be superior?

Also just looking for any general rules of thumbs for adapting oven and/or stovetop recipes for the pressure or slow cooker settings on the Instant Pot.
