+# This hook runs `task sync` in the background at the end of each task command that mutates
+# the task db. The list MUTATING_COMMANDS has the list.
+#
+# Usage: simply copy this file to ~/.tasks/hooks, or whatever your hooks directory is
+# as specified in you taskrc file.
+#
+# Compatibility: This hook uses the Hooks V2 API (https://taskwarrior.org/docs/hooks2.html)
+# So, it works with TaskWarrior 2.4.3+
