+This is an initial attempt to make it easier to test the examples in the https.md
+doc
+
+at this point, it has to be a manual thing, and I've been running it in boot2docker
+
+so my process is
+
+$ boot2docker ssh
+$$ git clone https://github.com/docker/docker
+$$ cd docker/docs/sources/articles/https
+$$ make cert
+lots of things to see and manually answer, as openssl wants to be interactive
+**NOTE:** make sure you enter the hostname (`boot2docker` in my case) when prompted for `Computer Name`)
+$$ sudo make run
+
+start another terminal
+
+$ boot2docker ssh
+$$ cd docker/docs/sources/articles/https
+$$ make client
+
+the last will connect first with `--tls` and then with `--tlsverify`
+
+both should succeed
