+Sample plugin for VPP
+=====================
+
+Overview
+--------
+
+This is the VPP sample plugin demonstrates how to create a new plugin
+that integrates with VPP. The sample code implements a trivial macswap
+algorithm that demonstrates plugin runtime integration with the VPP
+graph hierarchy, api and cli.
+
+For deeper dive information see the annotations in the sample code
+itself. See `sample.c <@ref%20sample.c>`__
+
+How to build and run the sample plugin.
+---------------------------------------
+
+Now (re)build VPP.
+
+::
+
+ $ make wipe
+
+Define environmental variable ‘SAMPLE_PLUGIN=yes’ with a process scope
+
+::
+
+ $ SAMPLE_PLUGIN=yes make build
+
+or a session scope, and build VPP.
+
+::
+
+ $ export SAMPLE_PLUGIN=yes
+ $ make build
+
+Now run VPP and make sure the plugin is loaded.
+
+::
+
+ $ make run
+ ...
+ load_one_plugin:184: Loaded plugin: memif_plugin.so (Packet Memory Interface (experimetal))
+ load_one_plugin:184: Loaded plugin: sample_plugin.so (Sample of VPP Plugin)

+ cp -r src/examples/sample-plugin/sample src/plugins/newplugin
+ cp src/examples/sample-plugin/sample.am src/plugins/newplugin.am
+
+Add the following entry to the plugins section of ``src/configure.ac``.
+

+
+Add the following entry to the plugins section of
+``src/plugins/Makefile.am``
+
+::
+

+
+::
+
+ $ make wipe
