To use the spoiler extension, simply add the following tag to any article:

<spoiler>...spoiler information goes here...</spoiler>

This extension is based upon the spoiler extension by Brian Enigma (though heavily modified). Here is the source code for this MediaWiki extension in the incarnation that is implemented on this wiki:
