+LONG_DESCRIPTION = """
+``reciprocalspaceship`` provides a ``pandas``-style interface for
+analyzing and manipulating reflection data from crystallography 
+experiments. Using this library, it is possible to interactively work 
+with crystallographic data in Python, enabling easy integration  with 
+modern scientific computing libraries. ``reciprocalspaceship`` is 
+intended to support the rapid prototyping of new crystallographic methods 
+and custom analyses while maintaining clear, reproducible, and performant 
+code.
+
+Features of this library include:
+
+  - Crystallographically-aware ``pandas`` objects, datatypes, and syntax 
+    that are familiar to Python users.
+  - Convenient integration with `GEMMI <https://gemmi.readthedocs.io/en/latest/>`__ 
+    to provide built-in methods and support for developing functions that 
+    use space groups, unit cell parameters, and crystallographic symmetry 
+    operations.
+  - Support for reading and writing MTZ reflection files.
