 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Using a Platform as a Service (PaaS) can be a great way to deploy your Symfony
-app quickly. There are many PaaS - below are a few that work well with Symfony:
-
-* `Symfony Cloud`_
-* `Heroku`_
-* `Platform.sh`_
-* `Azure`_
-* `fortrabbit`_
-* `Clever Cloud`_
-* `Scalingo`_
+app quickly. There are many PaaS, but we recommend `Platform.sh`_ as it
+provides a dedicated Symfony integration and help fund the Symfony development.
