Talk:Citation option in your edit toolbar

Does anyone know how to install RefToolBar 2.0b on a mediawiki installation? Documentation leads one to Wikipedia Project Page for RefToolBar/2.0. However, since Wikipedia has already installed this feature, their Installation Section only states:

No installation required
RefToolbar 2.0 is now turned on by default for all users on English Wikipedia. You don't have to do anything to install it.

So... there is this big gap in the use of RefToolBar because mediawiki points to Wikipedia for installation and Wikipedia doesn't offer anything. It seems straightfoward, but gathering and creating all the necessary .js pages does not result in a successful installation.
