Write some documentation about auth_key and the JWT content

[vincentfretin]

See my comment here
Hubs-Foundation/dialog#8 (comment)
We need to have some documentation in this repository. I'll probably do a PR here once I get to implement it in my app.

FYI I updated the example in my naf-janus-adapter repo branch 3.0.x to generate a client id and set it with setClientId https://github.com/networked-aframe/naf-janus-adapter/blob/3.0.x/examples/index.html
You just need to change the url to your hosted janus and the example now works.
We didn't have any working example before in the naf-janus-adapter, this was unfortunate.

Thank you for this note. I was wondering why I couldn't get this adapter to work with an installed instance of the Janus gateway running; but I guess you need audio on for the rest of the data to stream ( I was trying to do this without streaming audio).

If you didn't see it, read the janus deployment doc I wrote networked-aframe/naf-janus-adapter#8
We can discuss on A-Frame slack if you have some issues setting it up.

Ah nice, didn't see that. Very helpful thank you.

I removed the content of my two comments. I moved the content and rewrote some paragraphs in the documentation there https://github.com/networked-aframe/naf-janus-adapter/blob/master/docs/securing-janus-with-jwt.md
