+<h1 align="center">FreeCAD Topological Naming (toponaming) Branch</h1>
 
+### About
+
+This branch is dedicated to integrating code that improves the [topological naming problem](https://wiki.freecad.org/Topological_naming_problem) in FreeCAD. There have been several attempts to address it over the years within FreeCAD. In reality, toponaming is an issue that no modern CAD software is fully immune to. This is because the solutions are complex. 
+
+Thanks to an independent developer named Zheng Lei ('realthunder'), who has gone the farthest in the effort of fixing toponaming in FreeCAD, and has provided a proof of concept fix in his own branch named 'Link' branch. 
+
+* FreeCAD toponaming git repository: https://github.com/FreeCAD/FreeCAD/tree/development/toponaming  
+* FreeCAD main ('master') branch: https://github.com/FreeCAD/FreeCAD/
+
+### Objective
+
+Per the FreeCAD developer meetings that occurred during the pre-release of v0.20, 'toponaming' was identified as one of the main targets for merge in the v0.21/v1.0 release cycle. 
+
+### Main developers
+
+* @realthunder
+* @wwmayer
+
+### Contributing
+
+During this development cycle there will be nightly builds provided for testers to test and report results back to the developers.
