+# Important note about localising NodeBB
+
+The files here are read-only and overwritten daily (if there are changes) by the
+helper bot [Misty](https://github.com/nodebb-misty).
+
+Our localisation efforts are handled via [our Transifex Project](https://www.transifex.com/nodebb/nodebb/),
+and any pull requests made to this directory will be automatically closed because
+localisations can go out-of-sync when edited directly.
+
+If there are non-localised strings and you cannot find them in Transifex, please
+[open a new issue on our bug tracker](https://github.com/NodeBB/NodeBB/issues/new)
+so we can take a look.
+
+Thank you for helping localise NodeBB!

-NPM INSTALL
-For now, language packs will be stored here. Eventually, will be moved to server side to allow for npm install-ability.
-When that happens, server code will generate compressed JSON language files in this folder.
