-# This is a 3 step process
+# What does this do.. and why?
-#   1. First we need to figure out whether to use wget or curl for fetching remote files
+# (and why is it so complicated?)
-#   2. Next we need to figure out whether to use unzip or tar for downloading releases
+#
-#   3. We need to actually install the stuff
+# What this does
+#
+#   1. Sets some vars and asks some questions
+#   2. Installs everything into a single place
+#      (inculding deps like node.js, with the correct version)
+#   3. Depending on OS, creates a user for the service
+#   4. Depending on OS, register with system launcher
+#
+# Why
+#
+#   So that you can get a fully configured, running product,
+#   with zero manual configuration in a matter of seconds -
+#   and have an uninstall that's just as easy.
+#
+# Why so complicated?
+#
+#  To support nuance differences between various versions of
+#  Linux, macOS, and Android, including whether it's being
+#  installed with user privileges, as root, wit a system user
+#  system daemon launcher, etc.
