+# Techlab - Bleeding Edge Prelude
+
+Techlab is a prelude aimed at maximising expressivity in Haskell.
+
+This is intended for serious Haskell power users who don't mind the ground moving under them. 
+
+Techlab values expressivity above all other concerns. We want to see how
+convenient and natural domain modelling can be made in Haskell. That is, we
+don't know exactly what the final form of this toolkit might look like, and we
+make no guarantees that anything you might want in a prelude won't be
+sacrificed in pursuit of shinier language elements and ergonomics.
+
+Techlab currently contains re-exports of chassis, a wide range of polysemy libraries, dhall,
+formatting and optics. Hobbyists who like polysemy will probably feel right at home here, and
+contributions are welcome.
+
+Very early release - nothing is namespaced well or comprehensively re-exported.
