I install the arquillian-addon by doing,

addon-install-from-git --url https://github.com/forge/arquillian-addon.git.

Then I  should see in forge the command arquillian-setup. But I  have to restart forge to see this command. Is this true  and is there another way?

Also in forge there is a list of addons. But this addon is not in that list, but is in my local git repo anf forge somehow sees is. Is this true?
