+Install
+-------
+
+The package on pypi is quadtweet, so the recommended installation is with pip
+
+     pip install quadkey
+
+Methods
+-------
+
+There are many straightforward methods, so I'll only go into detail of the unique ones
+
+* children()
+* parent()
+* is_ancestor()
+* is_descendent()
+* area()
+*
+
+###difference(to)
+
+Gets the quadkeys between self and to forming a rectangle, inclusive.
+
+###unwind()
+
+Gets a list of all ancestors in descending order by level, inclusive.
