Wiki recognizes three different kinds of links: Internal Links, External Links and References.
Note: The examples below show spaces around square brackets for clarity. Do not include those spaces.
A link to another federated wiki page can be created by typing the page name inside double square brackets. It is common practice to use title case conventions when naming pages.
A link to an ordinary web page is created by enclosing the page URL and descriptive text inside single square brackets.
A reference is a direct link to a specific resource on a specific site. It also has an editable field to describe the resource.
