+# PS1 - Primary prompt displayed before each command
+####################################################
+# The PS1 prompt is constructed piece-by-piece by concatenating each
+# component to the previous component. Parts of the prompt are colored
+# conditionally based on what kind of user is logged in.
+#
+# Breakdown of PS1 components:
+# [TTY#] [DATE TIME] [USER HOST] [DIR] >
+#
+# Example of what the prompt should look like:
+# [1] [2023-03-28 16:02:55] [user host] [/etc/portage] >
