Translations:Workbench creation/3/en

You need a folder, with any name you like, placed in the user Mod directory, with an file, and, optionally an  file. The Init file is executed when FreeCAD starts, and the file is executed immediately after, but only when FreeCAD starts in GUI mode. That's all it needs for FreeCAD to find your workbench at startup and add it to its interface.
