Extension talk:GuidedTour/Write an extension tour

Where is the actual text?
I don't understand where we are supposed to put the actual text that is called out by the keys in the "message" array. 75.69.118.163 17:19, 20 April 2013 (UTC)
 * In your extensions' internationalization file. E.g. for the GettingStarted extension, the file is GettingStarted.i18n.php.  If you're not working on an extension, you can write an on-wiki tour; see Guided tours/Write an on-wiki tour. Superm401 - Talk 20:12, 22 April 2013 (UTC)
