+Each plugin will run as a binary inside the vCluster syncer container. It is by default copied over from an init container.
 This is done to allow easier communication between vCluster and the plugins as well as provide certain capabilities such as high-availability out of the box.
-The plugin itself will contact the vCluster pod during startup to obtain the access credentials to the virtual and host cluster.
-The plugin controllers are started with these credentials, similar to how vCluster itself starts its resource syncers.
