# Custom jupyterhub_config.py snippets¶

Sometimes you need to customize TLJH in ways that are not officially supported. We provide an easy escape hatch for those cases with a jupyterhub_conf.d directory that lets you load multiple jupyterhub_config.py snippets for your configuration. You need to create the directory when you use it for the first time.

Any files in /opt/tljh/config/jupyterhub_config.d that end in .py will be loaded in alphabetical order as python files to provide configuration for JupyterHub. Any config that can go in a regular jupyterhub_config.py file is valid in these files. They will be loaded after any of the config options specified with tljh-config are loaded.
