+## ddev `post-import-db` hook
+
+I generally have import scripts that I ship either from other add-ons or
+specific to projects and those scripts usually download the database from within
+the container. Rather than downloading the database and then running
+`ddev import-db --file=` I wanted to provide a way so that either way runs all
+of my post-import-db commands both with the ddev import command as well as from
+any helper script from within the project.
+
+So the way this works is that you can run
+`/var/www/html/.ddev/pimp-my-shell/hooks/post-import-db.sh` from any script that
+will be run in the container and it will take care of running all scripts on
+`.ddev/pimp-my-shell/post-import-db.d/`.
+
+This also allows for other add-ons to add scripts to this directory so that they
+will be run.
