i woul dlike to add some comments here

• remove the mainsail part of it. VAOC will only be supported in the RatOS configurator. The mainsail fork is dead and wont work anymore with it
• i would completely remove the build guide for a VAOC deivce. thsi should only be a user guide, how to use the software
• also having such a huge amount of images, especially the big ones, will be super distracting on smartphones
