An oft-requested feature was the ability to have Markdown automatically handle
within-document links as easily as it handled external links. To this aim, I
added the ability to interpret [Some Text][] as a cross-link, if a header
named “Some Text” exists.
As an example, [Metadata][] will take you to the
[section describing metadata][Metadata].
Alternatively, you can include an optional label of your choosing to help disambiguate cases where multiple headers have the same title:
### Overview [MultiMarkdownOverview] ##
This allows you to use [MultiMarkdownOverview] to refer to this section
specifically, and not another section named Overview. This works with atx-
or settext-style headers.
If you have already defined an anchor using the same id that is used by a header, then the defined anchor takes precedence.
In addition to headers within the document, you can provide labels for images and tables which can then be used for cross-references as well.
