 # GUI Translation Demo
 
-A demo showing how Godot seamlessly enables
-the use of localized resources and texts.
+This is a demo of how a project can be internationalized. Translations are
+created in a CSV file and then imported into Godot.
+
+For correct display, the font used must contain the glyphs required by the
+target language. See the `fonts` folder for some fonts that you can use in your
+project. Godot can load system fonts as a fallback, but this is not supported on
+all platforms and the different visual design of system fonts can create
+inconsistencies.
+
+Godot allows internationalized text to change automatically when the locale is
+modified. Resources can also be set to internationalized alternatives and replaced
+automatically on locale change. This process is known as *remapping*.
+
+Both CSV and gettext (PO/POT) approaches are showcased. Use the button in the
+bottom-right corner to switch between the two approaches.
+
+The resouce remapping process with PO is the same with CSV. The in-game text translation
+process is also the same – use keys to fetch the appropriate translation.
+
+The main difference between PO files and CSV files is the way both of them store
+the translated data in their files.  Have a look at the `translations/po`
+and `translations/csv` folders to see the files involved.
+
+See [Internationalizing games](https://docs.godotengine.org/en/latest/tutorials/i18n/internationalizing_games.html)
+and [Localization using gettext](https://docs.godotengine.org/en/latest/tutorials/i18n/localization_using_gettext.html)
+for more information.
 
 Language: GDScript
