Do you mean through the interlanguage links at the bottom of pages, or just general linking to alternate language wikis?
 * If it's the former, you can request those here: Project:Interlanguage link requests
 * For the latter, just use either w:c:lang.wiki-name:pagename or u:lang.wiki-name:pagename format (where lang is the language code (eg fr) and wiki-name is the actual wiki's name, which is usually the same as the english wiki version)
