How much of your main world do you have figured out?

So, I am a super thorough builder, and I love having a lot of details about the world figured out, down to the colors of the leaves on the trees.<br>I also love the idea of having a lot of world figured out before any actual writing takes place, the build as much as possible beforehand attitude. <br>I am very into the idea of having a super thorough "bible" for my world with all sorts of information, maps, timelines and the like. <br>I am a bit of a completionist so I want to figure out a lot about the world. <br>In general, how much of your world is figured out, do you try to have everything figured out or not so much? <br>TLDR: How much of your main world do you have figured out?
