Description

updated to use correct jinja2 boolean values

Note

The special constants true, false, and none are indeed lowercase. Because that caused confusion in the past, (True used to expand to an undefined variable that was considered false), all three can now also be written in title case (True, False, and None). However, for consistency, (all Jinja identifiers are lowercase) you should use the lowercase versions.
