+# Shape Server
+
+Author: Jack Harley jackpharley@gmail.com / jharley@tcd.ie
+
+This is my submission for Assignment 1 for CSU44012 Topics in Functional Programming 2020/21
+
+My report containing background information, design choices, reflection, etc. is submitted separately as a PDF to Blackboard.
+
+Build/Run
+----------------------
+Build the project with `stack build` and execute with `stack exec ShapeServer`.
+
+Then visit http://localhost:3000/ in a web browser.
