Many APISite and DataSite methods are thin wrappers around a module of the MediaWiki API, and the docstrings for these methods should include a link to the API:<foo> pages on http://mediawiki.org/wiki/API:Main_page
Links should be added using sphinx syntax.
Easy CGI Task: Find three APISite or DataSite methods which are a thin wrapper around a module of the MediaWiki API , and add the appropriate link to the docstring.
Either submit one changeset to Gerrit combining all three amendments, or submit three changesets to Gerrit containing only one amended docstring.
