 ### How to support a new language?
 
-1. prepare the translation source file
+1. Prepare the translation source file

+You need to add a language header file `language_xx.h`, replacing xx with the language/country code. (e.g., "en" for English). You can start with a existing language file by copying it to a new location:

-Then you can replace the strings in the macro _UxGT().
+Then simply replace the strings inside the `_UxGT()` macros.
