Hi,
There are many packages available for download and many of those packages do not have much information about them. However, there should be more examples on our wiki page in the future. Also, since RutOS is based on OpenWRT, you should be able to find a lot of useful information regarding some of the packages by looking for OpenWRT information.
Is it something specific that you are trying to achieve?
Regarding the German Language package, thank you for your feedback. It will be considered.
Kind Regards,
Andzej
