+You can also now make a **filter for languages**, though it is still not very user friendly. Subloader now tries to read from a file called lang.cfg that should be located in the installation directory. To configure it, make a file called `lang.txt` and open it with Notepad. In it write your desired languages, each in a new line, in English. It's not case sensitive. Then copy it to the Subloaders installation directory. For example:
+```
+english
+german

I will probably implement some simple text file setting for a language filter on client side, and not by using OS API, to avoid this problem and avoid adding clutter to the UI.
