install Yiddish spell checking

Hello,

I just installed a debian-kde OS on my computer, I am by no means a 
linux specialist, and I'd like to have a Yiddish spell-checking.
Aspell 60.7 is included in the distribution.

Many aspell dictionaries are available via the software manager apper, 
but not the Yiddish one.
I downloaded it there:
ftp://ftp.gnu.org/gnu/aspell/dict/0index.html
and read the README file, but I don't understand everything and still 
don't know how to install it.

Is there a place where I could find simple instructions to install this 
dictionary, or a way of adding it to available packages?

Regards
Helene
