There are some Tutorial Videos in the Video list accessible at the top of the forums from the Menu buttons Vidoes which may be of some help.
Bear in mind that Reloaded updates may change the way things need to be done somewhat but generally speaking in the main you should get a fair idea from them of some of the basics which are similar to most engines in many instances.
I think there are some help files in the Docs folder in the Reloaded install that may have some basic info.
A lot of helpful info at threads in the forums to but you have to look for what you want and perhaps search.
Many users are very helpful and will do so if you post your questions.
Not sure what if anything may be helpful to you in the FAQ menu item button at the top of the forums.
Other than that no official Manual as such as yet and probably for quite some time yet, but most things that can be done are covered somewhere in the forum posts to date.
If you find some helpful tutorials/info then the best way perhaps to find out what you need to do is just try some of the things in test levels and just have a go at everything you can find to play with and you will soon get the hang of the basics at least. More advanced features may take longer to master and there are some bugs and issues to consider and live with as its still very much a WIP (beta).
I could do with some help myself....
