[factually inaccurate?]
This documentation is transcluded from Template:Fact/doc.
Usage
This template marks sentences in the Scratch Wiki that may not be correct. This template is used like {{citation needed}}. Placing it in front of a sentence and after punctuation will put a superscribed piece of text next to the sentence, to mark that an editor will need to verify the text. This template is not like the citation needed template; this template is used to mark blatant mistakes.
Custom Message
If the first template parameter is defined, it will display that message instead. For example, type {{fact|when?}} to get [when?].
