1. In the directory /modules/ create a directory "avren", you will have /modules/avren/

Your module:
It must be a "hebrew" folder which contains the files 'data' - 'install' - 'template'
You must upload the folder your module "hebrew" in /modules/avren/
You will have in the end /modules/avren/hebrew/ => 'data' - 'install ' - ' template '

NOT

/modules/avren/hebrew/hebrew/  => 'data' - 'install ' - ' template '

I am attaching the example of my "french" file, I can not be clearer ...
