+# Instructions for usage
+# ----------------------
+# 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="data-hal-jessie" .
+# % docker run --rm -i -t -v $(pwd)/..:/code:rw data-hal-jessie:latest bash
+#
+# Use the existing docker image:
+# % docker pull docker1.mgm.sipwise.com/data-hal-jessie
+# % docker run --rm -i -t -v $(pwd)/..:/code:rw docker1.mgm.sipwise.com/data-hal-jessie:latest bash
+#
+# Inside docker (the command is in history, just press UP button):
+#   ./t/testrunner
