 Although it works, it is very slow, so we do not recommend it.
 
 A more rapid approach is to follow the **Unstable installation** method, as this
-provides all dependencies for you out of the box.  Then, we can replace certain
-Python files that tend to be updated frequently with those from the Git
-repository. We're going to use symlinks (Windows users can use ``mklink``), so

-In addition, we're also going to replace the Python code of the IfcOpenShell
-dependency with our Git repository, since most of the BlenderBIM Add-on
-functionality is agnostic of Blender, and is actually part of IfcOpenShell.
-Therefore, we need to keep this dependency highly updated as well.

 Blender for the changes to take effect.
