That is a Problem since the Release of rFactor in the Year 2005, no official Manual/Documentation. And that we still have to edit Files, to get some Things working as wanted, is also not the optimal Situation. So as a Newcomer to this Game, you have to search the Web and ask here in the Forum or elsewhere, like the Discord (that i don't use for Example) or you go the "Try and Error" Way, that we all do love so much. All Information is available, but spread all over the www. So it's hard to find sometimes. But i think that 98% of the Problems can be solved with the Help of the Community.
