-The <<.attr template>> attribute defaults to $:/core/ui/testcases/DefaultTemplate but can be used to specify a custom template for special purposes. The provided template $:/core/ui/testcases/RawJSONTemplate can be used for debugging purposes to display all of the payload widgets in JSON.
+The <<.attr template>> attribute defaults to $:/core/ui/testcases/DefaultTemplate
+
+The default template uses several variables that can be set by the user:
+
+|!Variable |!Description |
+|<<.var linkTarget>> |Causes the testcase description to be rendered as a link to the current tiddler |
+|<<.var displayFormat>> |Defaults to "wikitext", can also be "plaintext" to force plain text display |
+
+A custom template can be specified for special purposes. For example, the provided template $:/core/ui/testcases/RawJSONTemplate just displays the payload tiddlers in JSON, which can be used for debugging purposes.
