Help for Aimeos

Hello everybody) Yesterday I translated all aimeos admin panel into ru language. Now I want to do it for front-end part of my site. As I understand it already translated and I have just set language. But I do not know how to do it.
I visited this link https://aimeos.org/docs/Laravel/Add_loc ... tor#Routes and tried some variants, but it do not work. Can somebody help me? Can you write simple example for me ? In advance I am very grateful!

I am use aimeos last updating, php-7 and windows 7 os

So, can somebody help me translate or set ru language in client part of site? For example in list route page or in myaccount page ? I need to translate all client part. Admin part I already translate

If you want to make Russian to the default language in the frontend, make sure it's the only entry with position 0 in the Locale tab of the expert mode admin interface:

Thank you, aimeos! But I just did it as you said. I set 0 position in expert mode in locale->list for German language but site still in English language. Nothink happen. And tell me please how I can add here new language and activate it ?

As you can see links in "attributes" translated into German but other did not translated. I need know how I can add new language and translate all frontend)
