+Host stack test framework
+-------------------------
+
+For building docker image run `make` first and `./test` to run all the tests.
+`./test` script is basically a wrapper for `go test` and accepts its parameters,
+for example following runs a specific test: `./test -run Veth/EchoBuilt`.
+
+Root privileges is required to run tests as it uses linux `ip` command for
+configuring topology.
