This is how a track should be posted (you can copy & paste this and fill in you specific data):
-Track type: (permanent/temporary/dirt/oval etc.)
-maybe typical laptime with robot xyz
-Track outline image:
-origin: real-world copy (if yes which antetype) or fantasy
-link in one part (if too big uploaded somewhere else)
-maybe installation manual (normally very simple copying into correct folder but who knows...)
-a video of the track would be great but is relatively difficult to create with SD at the moment.
-IMPORTANT: License (is your track a conversion from an existing game? is it gpl? copyright?
comments and additions are welcome.
