+# Examples:
+# `sharefile`
+#   calling without arguments allows you to first select a folder and then
+#   a file from the folder to share.
+# `sharefile ~/my-file.zip`
+#   calling with a file as argument automatically uploads the file and copies
+#   share link to clipboard.
+# When called with a folder as argument allows you to select file within, uploads it and copies share link.
