Everything you need to get started is in the Easypaint folder.
The Word "paintmap" document shows how the texture map has been painted so you can get started.
Also included is the Paint Shop Pro/Adobe Photoshop layered image. This contains sevral layers and you can paint your texture on the background layer insert a new layer just above the background. The outline layer corresponds to the paintmap and should be hidden before exporting/saving as a bmp. The required textures are the textures on the aircraft such as wheels etc and should not be painted over (including the black panel on the left wing.
Finally the lineage layer is all the other extra detailing sema etc.
