The manual scimps over everything. It is like the creator of CKforms does not want to say what is for what, or how things are done. Especially, how to use the forms in an Article is unusually cryptic and does not work if done exactly as written. Apparently, 'some obvious thing that everybody knows' has been left out, making it an impossible tools for newbees.
Although there is a stylesheet, there is no control over layout in an early stage, especially the width of a label column can't be specified which is rather odd as that is the key layout element. So, the programmer made a brilliant extension but a very bad manual.
