A more extensive and updated project intro in the README

[consideRatio]

I'd love to use and contribute with maintenance of this project, but I struggle to understand enough about it to feel confident on how to install it etc.

Here are some points that i think could be addressed within the README:

• TightVNC is mentioned, but it is TigerVNC that is vendored in (a fork of TightVNC).
• websockify is a required dependency, but that is not documented
  • pip install of websockify doesn't seem to cut it, but conda install -c conda-forge does. Perhaps that is why it is not listed under install_requires in setup.py?
• __init__.py points to share/xstartup, which in turn does exec /usr/bin/dbus-launch xfce4-session, making me think that the apt packages dbus-x11 and xfce4-session are strictly required.
• What apt packages are required?
  As xfce4-session is required, perhaps is xorg (x11?) and other xfce4 packages strictly required as well?
• A "how it works" section like in jupyterhub-idle-culler's README
  Having an explanations of how it works technically could help me a lot to use and contribute to this project!
• Is the Dockerfile supposed to be used for binderhub, or is it a published artifact?
• Is the Python package published?
  If it is or should be, we should use a badge
  If it is not, why isn't it published and should it be soon?
• What is supposed to be exposed via the /panel path?

The README is a bit out of date, I'll work on it!

/panel: Nothing to do with this repo, do you have some other extension installed?

Thanks @manics! /panel confusion resolved

In [4]: from importlib import metadata
   ...: metadata.entry_points()["jupyter_serverproxy_servers"]
Out[4]: 
(EntryPoint(name='panel', value='panel_server:setup_panel_server', group='jupyter_serverproxy_servers'),
 EntryPoint(name='desktop', value='jupyter_desktop:setup_desktop', group='jupyter_serverproxy_servers'))

Ah, found it to be related to https://github.com/holoviz/jupyter-panel-proxy being installed.

I wrote https://github.com/yuvipanda/binder-desktop-app-template as a template that can be used to generate repos to launch specific GUI apps.
