+# Overview
+![travis-ci status](https://travis-ci.org/travitch/haggle.svg?branch=master)
+
+Haggle is a graph library for Haskell.  It aims to support large graphs
+efficiently and compactly.  It differs from
+[fgl](http://hackage.haskell.org/package/fgl) in a few ways:
+- There are no partial functions in the API
+- There are multiple graph representations included
+- Mutable graphs can be constructed in IO or ST
+- Labels for both nodes and edges are optional
+
+The API is based on typeclasses to allow programs to be written generically and
+support multiple graph representations when possible.  Graphs can be mutable,
+immutable, or inductive.
+
+The mutable graph support is designed to allow graphs to be efficiently
+constructed in a mutable context and then frozen into a pure immutable form.
+There are multiple representations of mutable and immutable graphs to support
+different use cases (simple graphs, directed graphs, and bidirectional directed
+graphs).  The different representations allow users to make decisions on time
+and space tradeoffs based on their algorithmic needs.
+
+Inductive graphs (the fgl style) are also supported, while sharing some of the
+API with the compact immutable graphs.
+
+See the haddocks in Data.Graph.Haggle for information and examples on using the
+API.
+
+# TODO
+- Reach feature parity with the algorithms in fgl
+- Explore more graph representations
+- Explore graph serialization (the use of the opaque `Vertex` type makes it a bit tricky)
