Some time ago i had used the Starterkit(never finished). A few weeks back i was looking into what i had done before... but i noticed that almost no add-ons use this.
So i checked https://wiki.freecad.org/Workbench_creation and there is no text reference to this kit(only link at the end of the page).
If this is still the prefered method to start a (python )Add-on / WB i have two requests:

• Pin the freecad.workbench_starterkit
• Add a additional topic / chapter in the Workbench creation page / Power users hub page

If this is not the prefered method anymore..

• Update the Readme.md file
