 [[WikiLink]], just put the name of the page to link to in double brackets.
 For example "\[[WikiLink]]".
 

+The file name associated with a wiki link is create as follows: capital
+letters are converted to lower case and spaces to underscores.  Finally,
+the file extention is added.
+

 If you ever need to write something like "\[[WikiLink]] without creating a
 wikilink, just prefix it with a "\", like "\\\\[[WikiLink]]".

-While a WikiLink is limited to alphanumerics and only a few special
-charaters, it is possible to create page names containing other characters:
+Also, if the file linked to by a WikiLink looks like an image, it will
+be displayed inline on the page.

 
 

-* 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.
+WikiLinks are matched with page names in a case-insensative manner, so you
+don't need to worry about getting the case the same, and can capitalise
+links at the start of a sentence, and so on.

+It's also possible to write a WikiLink that uses something other than the
+page name as the link text. For example "\[[foo_bar|SandBox]]" links to the
+SandBox page, but the link will appear like this: [[foo_bar|SandBox]]
