Translations:Translation for developers/4/en

You need to have a few things in mind:
 * Kiwix translation files are all in the "kiwix/chrome/locale" directory.
 * There is two types of translation files to translate the User Interface (Have a look to the *.js and *.xul file in kiwix/chrome/content/main to understand how it works):
 * "main.dtd" which provides translations for all *.xul files
 * "main.properties" which provides translations for all *.js files.
 * Translatewiki translations are imported separately in the Kiwix code repository on time a week and we always need to synchronize thus files with Kiwix code in both direction (KW->TW and TW -> KW).
