+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)
+   load_one_plugin:184: Loaded plugin: nat_plugin.so (Network Address Translation)
+   ...

+
+How to create a new plugin
+--------------------------
+
+To create a new plugin based on the sample plugin, copy and rename the
+sample plugin directory and automake config.
+
+::
+
+   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``.
+
+::
+
+   PLUGIN_ENABLED(newplugin)
+
+Add the following entry to the plugins section of
+``src/plugins/Makefile.am``
+
+::
+
+   if ENABLE_NEWPLUGIN
+   include newplugin.am
+   endif
+
+Now (re)build VPP.
+
+::
+
+   $ make wipe
+   $ make build
+
