Guides a leader of Taoists visiting places of worship (9)

'guides' is the definition.
('template' can be a synonym of 'guide')

'a leader of taoists visiting places of worship' is the wordplay.
'leader of' indicates taking the first letters.
'visiting' means one lot of letters goes inside another.
'places of worship' becomes 'temples' (I've seen this before).
The initial letter of 'taoists' is 't'.
'a'+'t'='at'
'at' inserted within 'temples' is 'TEMPLATES'.
