467 write a short readme on how to start the dashboard

[laurasootes]

I wrote a short readme for the usage of the dashboard. Please let me know if this is what you had in mind, or if it needs to be extended

Very nice, thanks!

Only the linting gives headaches.

Just wanted to add that this does not work for me:

python dashboard/dashboard.py

It gives this error:

Traceback (most recent call last):
  File "/home/stef/python/dianna/dashboard/dashboard.py", line 12, in <module>
    import layouts
  File "/home/stef/python/dianna/dashboard/layouts.py", line 10, in <module>
    encoded_image = base64.b64encode(open(image_filename, 'rb').read())
FileNotFoundError: [Errno 2] No such file or directory: 'app_data/logo.png'

This does work:

cd dashboard
python dashboard.py

@stefsmeets , did you edit/mention it in the documentation?
