where is the documentation for Saka-key?

[joefiesta]

The Firefox addon's page for Sakakey states:

"● Learn how to use Saka Key at https://key.saka.io and view the source code at https://github.com/lusakasa/saka-key

At that first website, there is virtually nothing. It has a firefox tab, and all that does is take you back to the Firefox addon page for Sakakkey. I want to find explanations for all the settings.

When one gfoes to https://key.saka.io there is virtually nothing there. And, clicking on the Firefox tab only takes one to the VERY SHORT synopsis at Firefox.

There should be explanations somewhere of what all the commands do. (Well, certainly, for those that are not totally obvious).
For exaple:

BLACKLIST - what is a blacklist? if you google "blacklist" you won't find a computer term.

TOGGLE PIN TAB - what does this do? I have no idea. What is a PIN TAB?? Is this a term Saka-key invented?
