WikiLinks provide easy linking between pages of the wiki. To create a
-WikiLink, just put the name of the page to link to in double brackets. For
-examples "[[ WikiLink ]]" (without the added whitespace).
+[[WikiLink]], just put the name of the page to link to in double brackets.
+For example "\[[WikiLink]]".
+
+If you ever need to write something like "\[[WikiLink]] without creating a
+wikilink, just prefix it with a "\", like "\\\\[[WikiLink]]".
Note that there are some special [[SubPage/LinkingRules]] that come into
play when linking between [[SubPage]]s.
WikiLinks can be entered in any case you like, the page they link to is
always lowercased.
+
+While a WikiLink is limited to alphanumerics and only a few special
+charaters, it is possible to create page names containing other characters:
+
+* To display a page name with a space in it, use "_" in the WikiLink, for
+ example, [[Multi_Word_Page_Name]].
+* For any other special character, you can use "__nnnn__" where `nnnn` is the
+ unicode character number. For example,
+ [[This_page_name_is__44___uselessly__44___a_complete_sentence__46__]]
+ Limiting use of this to when you really need it is a good idea.
+
+Note that if the file linked to by a WikiLink looks like an image, it will
+be displayed inline on the page.
