 ## Quickstart Installation Guide
 
-The quickstart installation method for Multus requires that you have first installed a Kubernetes CNI plugin to serve as your pod-to-pod network, which we refer to as your "default network" (a network interface that every pod will be created with). Each network attachment created by Multus will be in addition to this default network interface. For more detail on installing a default network CNI plugins, refer to our [quick-start guide](docs/quickstart.md).

 ## Thin Plugin v.s Thick Plugin
 
-With the multus 4.0 release, we introduce a new client/server style plugin deployment. This new deployment is called ['thick plugin'](docs/thick-plugin.md), in contrast to the previous deployment, which is now called 'thin plugin'. The new thick plugin consists of two binaries, multus-daemon and multus-shim CNI plugin. The 'multus-daemon' will be deployed to all nodes as local agent and supports additional features, such as metrics, which were not available with the 'thin plugin' deployment before. Due to those additional features, the 'thick plugin' comes with the trade-off of consuming more resources than the 'thin plugin'.
