Phpbb module install ? help

Hi hi how can I install the module phbb

I can install Joomla module but not install phpbb


This might help, please see page 148 of the user manual.

He means that how can i install custom mod into the phpBB? For example Automod or language pack or something thousands mods else. For installing mods we should have access phpbb root directory. So we can put the mod files into the install directory after unpack. How can we do that? Or is there any alternative way install the mods? 

There should be some way to do this. Otherwise not necessary to install phpBB forum utility into the EX4. Because without mods this is just core, not useful even i can say as a lttle bid more than nothing.
