.. note:: Technically, there's nothing stopping you from installing this on
31+
your robot, as there is a python interpreter available on the

roboRIO (RobotPy). However, due to FRC bandwidth limitations,
33+
it's probably best to run the UI + server on your driver station

Why make an HTML/Javascript dashboard?
37+
======================================
38+
39+
**TL;DR**: It's simpler.
40+
41+
pynetworktables2js lowers the barrier of entry for teams that want an
42+
additional way to tune/control their robot with a minimal amount of
43+
programming.
44+
45+
Lots of students and mentors know how to create simple web pages to display
46+
content, and there's lots of resources out there for creating dynamic content
47+
for webpages that use javascript. There is a lot of visually appealing
48+
content that others have created using web technologies -- why not leverage
49+
those resources to make something cool to control your robot?

Contributing new changes
73+
========================
74+
75+
pynetworktables2js is intended to be a project that all members of the FIRST
76+
community can quickly and easily contribute to. If you find a bug, or have an
77+
idea that you think others can use:
78+
79+
1. `Fork this git repository <https://github.com/robotpy/pynetworktables2js/fork>`_ to your github account
80+
2. Create your feature branch (``git checkout -b my-new-feature``)
81+
3. Commit your changes (``git commit -am 'Add some feature'``)
82+
4. Push to the branch (``git push -u origin my-new-feature``)
83+
5. Create new Pull Request on github
84+
85+
One place in particular I would love to see contributions is in adding useful
86+
javascript functions/objects that make creating dashboards even easier!
