Also I would like to translate on russian language, but I don't know what exactly files need to translate.
Look at the metadata file (config/metadata.config.php) of this application (in local/applications/noviusos_templates_basic). You will need to fill the template key. I suggest you to look at the old documentation (new documentation is underway and will come out in the days to come).
Please note that this is old documentation and it will be soon removed.
Don't hesitate to ask any other question
I am interesting, is any possible to import or integrate web templates (html5,css3) on Novius OS?
If is answer yes, could you explain how?
