 # EZ Installer. Run from the bash command line:

-# Installs into /usr/local/sdm by default

+# $1: Branch to install from (D:V8.6)
+# $2: Target install directory (D:/usr/local/sdm)
+# ** To use either of these arguments you must download this script to your system
+#    and start it from the command line:
+#    e.g., bash$ EZsdmInstaller V9.0                       # Install V9.0 release to /usr/local/sdm
+#          bash$ EZsdmInstaller "" /home/$(whoami)/sdm     # Install master branch to /home/$(whoami)/sdm
+#
+# NOTE: Using this version on the master branch requires that the master branch is updated to V9.0 (NYI)
 #
 # At the moment requires apt-based package installs. Easy to fix, of course. It's only code...
