+Exchange the placeholders with your actual config.
+``--jira-tag`` is mandatory.
+``--auto`` can be omitted or changed to ``--always`` to always prepend JIRA tag to
+commit msg even when its already there.
+``--deactivate-with`` takes a string which, when present at the start of the commit msg,
+deactivates adding the JIRA tag to commit msg and removes the string from the commit msg.
+``--no-error`` silences the error which occurs when the current branch has no JIRA tag.
