Add instructions for creating the config.json via a single terminal
command.
Reasoning - Assisted a MacOS deploy where they had everything setup
correctly but when they made the config.json file their instance
crashed, this was due to using the default GUI text editor which saved
the file as a .rtf and they renamed to .json. Doing this will leave
metadata in the file and actual wont know what to do with it causing an
infinite restart loop.
This addition provides a simple method to create the file without the
possibility of extra formatting bits causing issues
Reformatted the page, reworded some paragraphs, and added more
information about Docker for clarity.
After having to go through these steps myself, I found it might be
helpful to merge some of my suggested changes for others to view.
Hey, since I've been using Actual via Traefik for a few days now, I took
the time to add a little bit to the documentation in that regard. I hope
it fits so far. Please feel free to comment/improve anything.
