+This is a reimplementation of Xenomapper [1] in Haskell.  Unlike the
+orginal it is significantly more focused in scope: only primary specific
+alignments are output.
+
+Example usage: "xenomapper-hs primary-specific.bam primary.bam secondary.bam"
+
+The first argument is the output bam path, and the subsequent are the
+primary and secondary alignments. NB: the inputs must be name sorted
+and the output will be name sorted.
+
+Building the binary requires a flake enabled Nix [2]. Run
+
+  nix build git://vk3.wtf/xenomapper-hs.git
+
+to build, or if you have already cloned the repository then simply
+
+  nix build
+
+in the root.
