+# This script was created to automate the install of discord on your system.         #
+# It installs it separately from a package manager (snap, apt, dnf, etc), so this    #
+# can be used to install it on any linux system regardless of distro                 #
+# as long as the OS & processor supports it.                                         #
+#                                                                                    #
+# This script was originally just setup to handle installing or updating the         #
+# existing installation. It can be setup in crontab to handle it automatically so    #
+# you never have to manually do it again. All you have to do is add it to your       #
+# crontab to run daily or hourly (assuming you have a cron service installed)        #
+#                                                                                    #

+# eventually I am wanting this script to also provide additional functionalities:    #
+# - Install BetterDiscord                                                            #
+# - Handle multiple installations of discord (makes named config directories         #
+#   and will symlink them based on what "profile" you want to use). This will also   #
+#   allow you to have a installation that contains mods and others without.          #
+# - Handle manual configurations of discord (where applicable)                       #
+#                                                                                    #
