 The package-installs element allows for a declarative method of installing and
 uninstalling packages for an image build. Adding a file under your elements
-install.d directory called package-installs-<element-name> will cause the list
-of packages in that file to be installed at the beginning of the install.d
-phase.
+pre-install.d, install.d, or post-install.d directories called
+package-installs-<element-name> will cause the list of packages in that file to
+be installed at the beginning of the respective phase.
 
 If the package name in the file starts with a "-", then that package will be
 removed at the end of the install.d phase.
