How do Lokota Sioux make shelter?

Lokota Sioux were semi-nomadic Indians who lived in temporary villages that consisted of tipis. After a buffalo kill, they would use the brains to soften the hide so it wouldn't crack in the sun. They gathered long sticks 10 ft. long and held them up as they tied the sticks to the hide using buffalo tendons. There was a hole at the top to let out smoke from indoor fires. The tipis were very efficient and could be taken down in under 10 minutes.
