 ### Notes
 
+### Block design support
+
+If a block design is present, Tcl processes will be integrated in the project
+generator file to regenerate it.
+
+The script will also automatically create and add the BD wrapper to the project.
+
+The wrapper of the `.bd` file **must** be called `${bd_name}_wrapper`
+(e.g. `my_awesome_bd_wrapper` if your BD is called `my_awesome_bd`),
+which is the default when creating in the GUI with `Create HDL Wrapper...`.
+
+The BD wrapper that is automatically generated by Vivado **must not** be
+tracked by Git. If you need to manually modify the BD wrapper generated by Vivado,
+you can write a handwritten wrapper to the generated wrapper and put only the
+handwritten one under source control.
+
 #### Board part repository paths
 
 Only board part repositories inside the project are stored in the project
