+### Integrate Kandan on Heroku with your Amazon S3_BUCKET ( [Heroku article on AWS S3 to store static assets and file uploads](https://devcenter.heroku.com/articles/s3) ). Run the following line, replacing the the global variable values with your own:
+
+	heroku config:add S3_ACCESS_KEY_ID=xxx S3_SECRET_ACCESS_KEY=xxxx S3_BUCKET=bucket_name
+
+If successful you should get a response similar to:
+
+	Setting config vars and restarting myapp... done, v12
+	S3_ACCESS_KEY_ID: xxx
+	S3_SECRET_ACCESS_KEY: xxxx
+	S3_BUCKET: bucket_name
+
 Your app should be up and running now. The admin email by default is `admin@kandan.me` with password `kandanadmin`, or you can sign up as another user.
