+  description: |
+    IfcOpenShell
+    ============
+    
+    IfcOpenShell is an open source ([LGPL]) software library for working with Industry Foundation Classes ([IFC]). Complete
+    parsing support is provided for [IFC2x3 TC1], [IFC4 Add2 TC1], IFC4x1, IFC4x3, and IFC4x3. Extensive geometric support
+    is implemented for the IFC releases [IFC2x3 TC1] and [IFC4 Add2 TC1]. Extending with support for arbitrary IFC schemas
+    is possible at compile-time when using C++ and at run-time when using Python.
+    
+    In addition to a C++ and Python API, IfcOpenShell comes with an ecosystem of tools, notably including IfcConvert (an
+    application to convert IFC models to
+    other formats), the BlenderBIM Add-on (an add-on to Blender providing a graphical IFC authoring platform), and many
+    other libraries, CLI apps, and more. Support is also provided for auxiliary standards such as BCF and IDS.
+

 A simple Python implementation of the BCF standard. Manipulation of BCF-XML is
 available via `bcfxml.py` and manipulation of BCF-API is available via
 `bcfapi.py`.
+
+Python files in 'model' folder are automatically generated from .xsd files (located in 'xsd' folder).
+To regenerate them you can use `make models`.
+The only exception is 'v2/model/extensions.py', see it's note for the details.
