+Open Applied Topology (OAT) is a software package for begginers through advanced
+users in applied topology.
+It specializes in efficient, user-friendly tools to 
+
+- factor large matrices, and
+- expose factored matrices to users in Python and Rust. 
+
+This enables users to 
+
+- obtain cycle representatives for persistent homology
+- improve these cycles through optimization
+- develop new and different algorithms for analyzing topological data, e.g.
+  compute induced maps on homology
+
+**Please note** This library is actively developed, so new features may not yet
+be tagged on cat-list.
