OK, styling up your braids into a bun isn't some difficult task you will start thinking of using Ladder to climb a pole. If you think you can do it, then you can.
Bun is probably the most common way to style your braids into a chic Updo. The major advantage of buns is variability. High buns can be bulky or more compact, loose or tight.
To style into a bun, make a high ponytail, wrap with a beautiful band, then fold the braids from the pony base and wrap it round the pony base, then tuck in the braids and your good to go.
