Ok, I've been playing nexuiz for a while and I've been thinking of attempting to create a map,the thing is that im totally clueless on how to work the engine (I've made some DooM/HeXeN maps but hey this was only a 2,5d one!!).I have NetRadiant but I don't know to use it-I've searched the forums here for a detailed manual but with no results and the problem is that this period I don't really have time to search and try on my own as I would do otherwise since I need to be studying hard to get to university

.So what I'm asking for pleaaaaase

is a link to a step to step guide/manual that starts assuming the user has zero knowledge of the tool.Thanks preactively!
PS.Posted it here instead of e.g General Discussion because I thought such a guide might be useful to other people in the future
