How to use Burrows?

[nai249]

I want my citizens to stay inside during sieges. Old forums and the tips/help pop up says this is how I do it. But it doesn't tell me HOW I do this. All the wikis and forums are out dated and I cannot find the "alerts". I see there are a bunch of unlabeled symbols in the burrows section but they're unlabeled and I have no idea what any of them mean.

Hey nai249,
So a Burrow is set up by pressing "U" that is a capital u.
You then "Add new burrow" and paint all the places you want to have in that burrow. Don't forget different Z-levels.
After the burrow is painted it lets you customize how it looks. This is just superficial as it can help for the people who like to have 30+ burrows in a fortress.
After customizing you press "Accept"
At this point the burrow is formed but no dorfs will be in it. So clickl the Assign dorf and do "Civilians: All"
Now you are nearly done. I'd recommend toggling OFF the ability for dorfs to source supplies from outside the burry.
You use the "Suspend this burrow" any time you don't want he dorfs to cower in place.

*Note, if you turn a burrow on, and a dorf already was on their way to do a job, they will try to finish that job FIRST. This can get them killed, so watch out, you may need to remove their job or enlist them in a squad to get them to "reset" their order.
