 This is an add-on section for region changing your console. This is done by installing the 11.15.0 CTRTransfer image for the region you want to switch to. After installing the image, you can update your console normally to the latest firmware (11.17.0).
 
-Note that region changing is almost completely unnecessary since Luma3DS supports out-of-region games and individual title [Locale Emulation](https://github.com/LumaTeam/Luma3DS/wiki/Optional-features). Additionally, running NDS games with alternative out-of-region languages is supported by [TWiLight Menu++](https://github.com/DS-Homebrew/TWiLightMenu/releases). You should only perform a region change if you wish to have your system UI is in a language that is not available on your console's current region.
