+Kiwi is an efficient C++ implementation of the Cassowary constraint solving
+algorithm. Kiwi is an implementation of the algorithm based on the
+`seminal Cassowary paper <https://constraints.cs.washington.edu/solvers/cassowary-tochi.pdf>`_.
+It is *not* a refactoring of the original C++ solver. Kiwi has been designed
+from the ground up to be lightweight and fast. Kiwi ranges from 10x to 500x
+faster than the original Cassowary solver with typical use cases gaining a 40x
+improvement. Memory savings are consistently > 5x.
+
+In addition to the C++ solver, Kiwi ships with hand-rolled Python bindings for
+Python 3.7+.
