 ## Initialization Scripts
 
 If you would like to do additional initialization, add a directory called `/docker-custom-entrypoint.d/` and fill it with `.sh` scripts.
 
 You can also create sub-directories in `/docker-custom-entrypoint.d/` for scripts that have to run at different stages.
 
+- `/docker-custom-entrypoint.d/pre-default/` - scripts that run before the default entrypoint scripts from this repo run.
 - `/docker-custom-entrypoint.d/` - scripts that run after the default entrypoint scripts, but before the puppetserver service is started.
 - `/docker-custom-entrypoint.d/post-startup/` - scripts that run after the puppetserver service is started.
 - `/docker-custom-entrypoint.d/sigterm-handler/` - scripts that run when the container receives a SIGTERM signal.
