Jupyter Notebook server extension that serves static files such as documentation files.
The basic e2x help in English and German is served under /e2xhelp/base/html/en and /e2xhelp/base/html/de.
By creating the config e2xhelp_config.py you can serve additonal files.
These files will be served under /e2xhelp/shared/.
The e2xhelp_config.py should be located in any of the Jupyter config directories. You can find out which directories these are by executing jupyter --paths in the terminal and look at the directories under config.
Example config:
# ex2help_config.py
c = get_config()
# Specifiy the path to your extra files
c.Help.shared_path = '/srv/shared_dir'
