What do the default templates look like? #500
Description
The alertmanager configuration documentation references templates for the defaults for various parameters, however it's not clear how to find what those templates actually are. Links to their individual definitions, or at least a sentence in each receiver configuration section "you can find the definitions for the (Slack|HipChat|Email|PagerDuty|etc) templates [here]" would be very helpful to a curious newbie such as myself.
