Welcome to the rFactor Wiki.
This is a community run Wiki which allows open editing.
The benefit of a Wiki over a Forum is that a Wiki page should reflect the current state of knowledge on a topic whereas a Forum requires you to trawl through numerous posts to try and piece together the relevant information.
Every Wiki page has an associated discussion page (see tabs at the top) that allows people to debate the topic and help them come to an agreement over the page content.
You can see how the page has changed overtime by looking at the history tab at the top. You can subscribe to a page to track changes by clicking on the watch tab.
To help structure the Wiki it maybe useful to name the pages according to some form of naming convention, so pages maybe named something like:
RFactor2 _ Track Guide _ Brianza
RFactor2 _ Track Guide _ Monza
RFactor2 _ Car Setup _ Geneeral Guide
RFactor2 _ Car Setup _ Renault
RFactor2 _ Controller Setup _ General Tips
RFactor2 _ Controller Setup _ G27
P.S. I only updated this because I'm finding it hard going through the forums trying to find out how to setup cars and controllers etc...(but as its a wiki you can delete or change this as you want)
