 # A script to bootstrap dokku.
 # It expects to be run on Ubuntu 14.04 via 'sudo'
+# If installing a tag higher than 0.3.13, it may install dokku via a package (so long as the package is higher than 0.3.13)
 # It checks out the dokku source code from Github into ~/dokku and then runs 'make install' from dokku source.
