Thank you Szabolcs. Of course you are right. With Math 11.0 or later the documentation of BIOKMOD (a few notebooks) need be opened by user directely. My recomendation is that the user have in a folder o subdirectory these notebooks. I will correct the file readme to clarify this point. The packages are compatible with version 11. On the other hand, the main functions of BIOKMOD can be run using BIOKMODWEB developed using webMathematica, so Mathematica is not requiered it can be run directely using a browser.

Perhaps you can tell me some recomendation to adapt the domentation help to the present style.

Just wanted to let you know that the documentation can no longer be viewed as described in the "readme" in Mathematica 11.0 or later, as it uses the old, pre-Mathematica-6.0 documentation style.

It can still be opened manually.

(Unfortunately, creating the new-style documentation is very different and somewhat troublesome.)

The Kernel/init.m file contains Get["`Biokmod`"], which seems to be invalid. This triggers only when trying <<Biokmod`. Perhaps this is not the intended way to load the package (I see that the examples load sub-packages instead), but it's what one would naturally try and what I tried first. Perhaps this can be changed so that <<Biokmod` will load all sub-packages at once?
