Translation of custom payment plugin

-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.4.3
-- PHP version -- : 5.5.9

Hello

I have just finished coding payment plugin, but i have problem with translations.
My plugin will be oficiall plugin, so it must have complete transtation after instalation.

Unfortunatly there is no available plugin(in standart hikashoppackage) with language files wich I can based on.
Based on hikashop and joomla documentation I tryed to include my own language file in plugin directory, but joomla didn't load my language file. I folowed
docs.joomla.org/Specification_of_language_files

How can I translate Label of plugin configuration?

Hello,
If you create your own extension/plugin, the translation won't be handled by Hikashop, so using some Joomla tutorials like this will probably help you : www.phoca.cz/documents/46-translation/20...or-joomla-extensions
