Good morning to everyone. Although I guess it will not be of interest to most of the list members, I wanted to communicate that I have written an introduction to ConTeXt Mark IV in Spanish, which can be downloaded at https://webs.um.es/jal/docs/introCTX.pdf. Its title is "An Introduction (not too short) to ConTeXt Mark IV". ConTeXt is a wonderful document composition system, but there is not much literature to help you get into it, hence my initiative. The problem is that I've only been using ConTeXt for a short time and still have many doubts, so it's possible that the introduction may contain errors. As it has been written in Spanish I don't think many of you will be able to read it, but I would appreciate, of course, any suggestions for improvement. The document is, on the other hand, free and anyone who wants to include it in any ConTeXt distribution can, of course, do so. Also, if anyone wants the source files, I have no problem providing them. I have not based my introduction on LMTX because I think that for beginners a more stable system, like LuaTeX, is preferable. Finally, I apologize for my bad English level. I read it reasonably well, but expressing myself in it is much harder for me. -- Joaquín Ataz López Derecho Civil Universidad de Murcia
