+# Generates some glue code for translation of /command hints.
+
+# How to use this:
+# - Add any new hints to assets/l10n/intl_en.arb
+#   They must be of the form commandHint_<command> with <command> in lowercase.
+# - Run this script to regenerate the glue code
+# - Run flutter test to see if you did everything right
+
+# Looking to add descriptions for a new command, but don't know what it does?
+# It is likely defined here (in registerDefaultCommands()):
