{{#invoke:Template link general|main}}

This module is used by {{Template link general}} and related templates to display links to templates. It is similar to {{Tl}} but with additional formatting options and the ability to include parameters in the display. See the Parameters section of the Template documentation subpage for the full list, which can be enabled by passing any value to them (such as "on", "yes", etc.).
