 Welcome to PySheaf's documentation!
 ===================================
 
+The PySheaf library is an experimental platform for computational and applied sheaf theory.   Have a look at the latest version at the PySheaf GitHub repository: `<https://github.com/kb1dds/pysheaf>`_
+
+Sheaves are managed by subclassing from :py:class:`CellComplex`, which is a little awkward as :py:class:`SheafCell` is subclassed from :py:class:`Cell`, etc.  However, the idea is that everything that can be done to the base space of a sheaf is inherited from its underlying :py:class:`CellComplex` structure.
+
+Sections of sheaves have their own :py:class:`Section` class.  Truly, the data structure does not self-check for consistency, so really they are more of an "assignment" or "serration" than a section.  However, they do know how to extend themselves.
