+# This program allows you to quickly open up any file you want in Sublime Text by selecting files
+# with the `fzf` fuzzy finder and then passing them to `subl`. Just run it and you'll see what I
+# mean!
+
+# STATUS: WORK-IN-PROGRESS! It works, but it needs some massive cleanup in the comments and I need
+# to generally clean up and refactor the code as necessary. It does work though, so feel free
+# to use it.
