+# chassis
+
+Chassis is an experimental prelude that exports most of the standard Haskell apparatus by default,
+common types and type classes, as well as lesser used abstractions from category theory by default.
+
+Chassis also re-exports some thins from vinyl and composite, and keeps polykinds on by default.
+
+Extremely early prototype idea.
