+### [cute-c2]
+
+[cute-c2] is a Rust wrapper, created by [yeahross0], for Randy Gaul's
+[single-header C library of the same name][cute-c2-c]. It implements 2D
+collision detection between circles, AABBs, capsules and up to eight-sided
+convex polygons.
+
+The API exposed is safe and Rust-y, and various examples are provided in the
+repository. The library is not yet published to Crates.io, but looks promising!
