+
+# plugins
+Some CNI network plugins, maintained by the containernetworking team. For more information, see the individual READMEs.
+
+## Plugins supplied:
+### Main: interface-creating
+* `bridge`: Creates a bridge, adds the host and the container to it.
+* `ipvlan`: Adds an [ipvlan](https://www.kernel.org/doc/Documentation/networking/ipvlan.txt) interface in the container
+* `loopback`: Creates a loopback interface
+* `macvlan`: Creates a new MAC address, forwards all traffic to that to the container
+* `ptp`: Creates a veth pair.
+* `vlan`: Allocates a vlan device.
+
+### IPAM: IP address allocation
+* `dhcp`: Runs a daemon on the host to make DHCP requests on behalf of the container
+* `host-local`: maintains a local database of allocated IPs
+
+### Meta: other plugins
+* `flannel`: generates an interface corresponding to a flannel config file
+* `tuning`: Tweaks sysctl parameters of an existing interface
+* `portmap`: An iptables-based portmapping plugin. Maps ports from the host's address space to the container.
+
+### Sample
+The sample plugin provides an example for building your own plugin.
