Hello Automakers. I've pushed the documentation work I've done so far to the temporary public branch "GSoC/experimental/docs-custom-test-drivers", in case anyone wants to take a look at it (I had hoped to finish it this morning, but I didn't, and I'll be AFK until this evening, so there's no point in delaying even more). Notice that that branch is bound to be amended and rebased, and finally deleted (it won't be merged in the 'test-protocols' branch, rather its changes will be re-applied on the top of that).
Regards, Stefano
