I want to install wordpress on heroku and follow this tutorial(https://github.com/mhoofman/wordpress-heroku) I downloaded the toolbelt of heroku and got the git repo on my disk I also created a heroku account but when I want to add postgresql to it i get:
$ heroku addons:add heroku-postgresql:dev
! autoupdate in progress
! No app specified.
! Run this command from an app folder or specify which app to use with --app
<app name>
Why I do everything as stated in the tutorial;?
I appreciate your answer
