-        # Prior to `v1.0.0`, this formula provided two methods for managing php; the   #

-        # has now been removed and `php.ng` has been promoted to be `PHP` in its       #
-        # place.                                                                       #

-        # To migrate from `php.ng`, simply modify your pillar to promote the entire    #
-        # section under `php:ng` so that it is under `php` instead. So with the        #
-        # editor of your choice, highlight the entire section and then unindent one    #
-        # level. Finish by removing the `ng:` line.                                    #
+        # If you are currently using `php.ng`, there is nothing to do until `v1.0.0`   #

-        # To migrate from the old `php`, first convert to `php.ng` under `v0.37.0`     #
-        # and then follow the steps laid out in the paragraph directly above.          #
