I am trying to install a language package in Latex not officialy included in TeX. I have downloaded the .LDF file and the hyphenation rules, but have no idea how to install them. I am using MixTex.
Under MiKTeX, I would create a
TeXMF-local directory (unless it already exists — MiKTeX does not create one by default), add it to the list of TeX roots (MiKTeX Szettings, Roots tab), then create a
TeXMF-local\tex\latex\babel-mylanguage chain of directories in it, in which I would put
mylanguage.ldf. If there is any documentation, I would put it in
There would remain to update the FNDB, with MKTeX Options.
