+Archinstall supports multiple languages, which depend on translations coming from the community :)
 
-New languages can be added simply by creating a new folder with the proper language abbrevation (see list `languages.json` if unsure).  
+## Important Note
+Before starting a new language translation be aware that a font for that language may not be
+available on the ISO. We are using the pre-installed font `/usr/share/kbd/consolefonts/LatGrkCyr-8x16.psfu.gz` in archinstall
+which should cover a fair amount of different languages but unfortunately not all of them.
+
+We have the option to provide a custom font in case the above is not covering a specific language, which can
+be achieved by installing the font yourself on the ISO and saving it to `/usr/share/kbd/consolefonts/archinstall_font.psfu.gz`.
+If this font is present it will be automatically loaded and all languages which are not supported by the default font will
+be enabled (but only some might actually work).
+
+Please make sure that the provided language works with the default font on the ISO, and if not mark it in the `languages.json`
+that it needs an external dependency
