+# When you want to build the base image from scratch (jump to the next section if you don't want to build yourself!):
+# % docker build --tag="janus-client-jessie" .
+# % docker run --rm -i -t -v $(pwd)/..:/code:ro janus-client-jessie:latest bash
+#
+# Use the existing docker image:
+# % docker pull docker.mgm.sipwise.com/janus-client-jessie
+# % docker run --rm -i -t -v $(pwd)/..:/code:ro docker.mgm.sipwise.com/janus-client-jessie:latest bash
