+## IMPORTANT
+
+Localization files are not stored into files!
+
+Contact us on Gitter to request access to the translation web service: https://gitter.im/Requarks/wiki
+
+## Development Mode
+
+If you need to add new keys and test them live, simply create a {LANG}.yml file in this folder containing the values you want to test. e.g.:
+
+### en.yml
+```yml
+admin:
+  api.title: 'API Access'
+  auth.title: 'Authentication'
+```
+
+The official localization keys will still be loaded first, but your local files will overwrite any existing keys (and add new ones).
+
+Note that you must restart Wiki.js to load any changes made to the files, which happens automatically on save when in dev mode.
