Hi, i am new to Wikibase. I want to populate a wikibase instance, but i need to delete first the data that is already there. i didn't install the instance but it was done with docker. Looking at this wiki it seems that the 'deleteAllData.php' script is what i need, but i didn't find it in the server. If someone could shed light on it and explain me how to delete the current database, i would really appreciate it. THANKS!
