+    Sitka is a built environment analysis and modeling library for Python.
+
+    This library is intended to make modeling and simulation for the built environment more hackable and easier to use for:
+
+    * Portable design tools
+    * Scalable web apps and services
+    * Quick design and analysis studies
+    * Interactive simulations and analyses
+    * Testing new models
+
+    The library is currently being written entirely in Python using [Pandas](https://pandas.pydata.org) as a core dependency in order to allow easier integration with data analysis in [Jupyter](https://jupyter.org).
+
+    A focus of this project is to create tools to make building models more hackable.  The library can be used to create a simple model just a few inputs or a larger whole building model can be created by connecting multiple objects.
