-# Soapine configuration
-To work and do what you told it to do, Soapine uses a configuration file.
-
-## Location
-Soapine will search for the configuration in:
-* `(boot partition)\soapine.cfg`
-* `(boot partition)\soapine\soapine.cfg`
-* `(boot partition)\EFI\BOOT\soapine.cfg`
-* `(boot partition)\EFI\soapine.cfg`
-
-If Soapine finds the config file, he parses it and jump to his usual menu. Else, Soapine will display a stop screen saying that you need to fix your configuration
-
-## Accepted value types
-* String literal (`"Hello, World!"`)
-* Decimal (`2`)
-* Hexadecimal (`0x2`)
-* Hexadecimal color (`#FFFFFF`)
-* Boolean (`true/false`)
-
-## Declarations
-Declarations are values that components of Soapine will search for:
-If you declare `VERBOSE` with a value of true, Soapine will itself put in verbose mode.
-
-You can do a declaration by writing the name + an equal sign + the value (using the accepted value types), that will make `NAME=VALUE`.
-
-If an unused declaration is provided (for example `FORCE_SOAPINE_TO_LIKE_ME=true`), Soapine will simply ignore it, but it will still be present.
-
-Here are some example declarations:
-* `MENU_BRANDING="Raphaël's Custom Soapine!!"` (string literal)
-* `MENU_HEADERBAR_BG=#FFFFFF` (Hexadecimal color)
-* `MENU_HEADERBAR_MARGIN=1` (decimal)
-* `VERBOSE=true` (boolean)
-* `LOAD_ADDRESS=0x1000` (hexadecimal)
-
-## Menu entries
-Menu entries allow you to show an operating system (that can be loaded with the supported protocols!) on the menu.
-They are declared like that:
-
-```c
-menu_entry "Project Jupiter" {
-
-};
-```
-*(yes i decided to give a C-like syntax to it)*
-
-You can put a small number of declarations inside the menu entries. (PROTOCOL, IMAGE_PATH, CMDLINE, RESOLUTION) (Providing the `PROTOCOL` and `IMAGE_PATH` declarations is required for Soapine to boot your OS!)
-
-## Supported declarations
-None for now (we just got the config parser working!)
-
-At least, you can still define entries!

-# Soapine's philosophy
-Soapine is meant to be lightweight, while being useful to everyone:
-
-* Ship the bootloader with multiple features (even the weirdest features)
-* Ability to extend the bootloader with ELF extensions: If you wanna write an extension to support PE loading, ***DO IT***.
-
-Soapine is also meant to be customizable:
-
-* You can modify each bit of the bootloader: If you wanna center the headerbar text, you ***CAN***
-* You can change the default values in Soapine's source code.

+# Translating AxBoot
+
+To translate AxBoot, copy `en_US.c` in the `common/i18n` directory and rename it (and the translation structure) to the target language code.
+Before translating each string, open `common/i18n/i18n.c` and register the new language:
+
+```c
