how to use the program NeoTextureEdit?

I can’t find a tutorial video, or any instructions anywhere

it looks like realy cool software I just don’t know where to start after opening it

It looks similar to mapzone http://www.mapzoneeditor.com/?PAGE=HOME
there is some documentation for mapzone, but it might be sparse.
In the sketchbooks section I left some tiling image textures that might be helpful to use with these programs.

Thank you sorry for taking so long to respond
