Documentation for v2

[NanderTGA]

Msgroom v2 is coming along nicely, but there's one big problem: documentation.
The plan is to write some proper documentation on the repository wiki.
Until I fix the other 2 issues and write some proper documentaton, v2 cannot release.

Current plan is to use docusaurus.
I also want to make a nice front page so wish me luck.

Current issues on the site:

• Meta tags still have default values.
  Might also want to look at the title.

• Edit page button not working
  I suspect this happens because our default branch is still called main instead of master.
  Now that we're talking about it, should we change the default branch name?

A quick google search tells us that companies want to eliminate divisive language or something and master is a term taken from slavery.
Looks like we're renaming the branch folks.
