You need to make sure the content stays valid LaTeX code, though. You may need to consult a LaTeX book or online documentation, e.g., the starter "clsguide.pdf" that comes with every LaTeX distribution. b) The cls file cannot be compiled directly, only documents using it can be compiled (this holds for both, LaTeX and LyX documents). To test your *.cls file, create a small LaTeX document and compile this "by hand". c) LyX adds a layer, the *.layout file that is an interface between the definitions in the *.cls file and what you want to see in LyX. See Help>Customization for details. Hope that gets you started. In case of problems, please ask giving a *minimal* example and the error message. Günter
