## <a name="Overview"></a> Overview
TWiki contribs extend the functionality of TWiki, typically used by plugins and add-ons. They may also provide alternative implementations for sections of the TWiki core e.g. user management, or when an extension just can't be implemented as a plugin because it requires very close access to TWiki internals.
