I already have elgg up and running but wanted to try the composer method.

Everything seems to work but one thing... there are no plugins what so ever installed by the installer.

In fact, there is no elgg/mod directory and nothing else that I can see.

If I copy the mod dir and all that's inside to the new install, then I see the plugins but maybe composer won't know anything about them if I do it this way?

Are there some other steps I'm supposed to take?
