 This might occur when you try to run the latest version of `edx-platform`, and not a version close to `gingko.master`. It is no longer necessary to patch the `LOGGING` configuration in the latest `edx-platform` releases, as indicated in the [development](#for-developers) section above, so you should remove the call to `get_logger_config` altogether from your development settings.
 
+### The chosen default language does not display properly
+
+By default, Open edX comes with a [very limited set](https://github.com/edx/edx-platform/blob/master/conf/locale/config.yaml) of translation/localization files. To complement these languages, we add locales from the [openedx-i18n project](https://github.com/regisb/openedx-i18n/blob/master/edx-platform/locale/config-extra.yaml). But not all supported locales are downloaded. In some cases, the chosen default language will not display properly because if was not packaged in either edx-platform or openedx-i18n. If you feel like your language should be packaged, please [open an issue on the openedx-i18n project](https://github.com/regisb/openedx-i18n/issues).

 ## Disclaimers & Warnings
 
 This project is the follow-up of my work on an [install from scratch of Open edX](https://github.com/regisb/openedx-install). It does not rely on any hack or complex deployment script. In particular, we do not use the Open edX [Ansible deployment playbooks](https://github.com/edx/configuration/). That means that the folks at edX.org are *not* responsible for troubleshooting issues of this project. Please don't bother Ned ;-)
