+Building
+----------
+
+1) Custom ODL Oxygen build:
+git clone https://git.opendaylight.org/gerrit/netconf
+cd netconf
+git checkout -b honeycomb
+git reset --hard release/oxygen
+# copy-config support:
+git fetch https://git.opendaylight.org/gerrit/netconf refs/changes/06/69606/1 && git cherry-pick FETCH_HEAD
+# ncclient support:
+git fetch https://git.opendaylight.org/gerrit/netconf refs/changes/81/71181/1 && git cherry-pick FETCH_HEAD
+mvn clean install -pl netconf/netconf-util,netconf/netconf-netty-util,netconf/mdsal-netconf-connector
+
+2) Build vpp-integration module from hc2vpp project:
+cd hc2vpp
+mvn clean install -pl vpp-integration/minimal-distribution
+
+3) (optional) Build honeycomb package
+./packaging/deb/xenial/debuild.sh
+
+4) Build ncclient
+git clone -b honeycomb https://github.com/marekgr/ncclient.git
+cd ncclient
+sudo python setup.py install
+
+
+Running examples
+----------
+
+ACL:
+./acl/test_acl.sh
+./acl/test_acl_updates.sh
+
+NAT:
+./acl/test_nat.sh
+./acl/test_nat_updates.sh
+
+Suggestions:
+Remember that HC by default persists config and restores it after restart.
+You can disable this behaviour using config/honeycomb.json.
