+### Plugins<a id="Plugins"></a>
+
+TShock, like most other administration modifications, allows the use of plugins. Logically, all plugins go in the *serverplugins* folder, and can be **either .dll or .dll-plugin** files. TShock is itself a plugin on the TerrariaServerAPI.
+
+You can find all plugins on the [forums](http://tshock.co/xf/index.php?forums/plugin-releases.15/), and the documentation for creating plugins can be found on the [wiki](http://develop.tshock.co:8080/display/docs/Plugin+Development).
