 Built-In Plugins
 ================
+
+Planetary.js comes with several built-in plugins that provide a base set of functionality. (Note that the `planetaryjs-noplugins.js` file, as its name suggests, does not include the plugins). They are described in detail on their own pages, but are:
+
+* [Earth](/documentation/builtin_earth.html) - a combination of the `topojson`, `oceans`, `land`, and `borders` plugins.
+* [TopoJSON](/documentation/builtin_topojson.html) - loads TopoJSON data via Ajax (or via configuration) and makes it available for use by other plugins
+* [Oceans](/documentation/builtin_oceans.html) - fills in the globe with a solid color (and an optional stroke)
+* [Land](/documentation/builtin_land.html) - uses data from the `topojson` plugin to draw Earth's land masses
+* [Borders](/documentation/builtin_borders.html) - uses data from the `topojson` plugin to draw borders between Earth's countries
+* [Pings](/documentation/builtin_pings.html) - draws animated, circular pings on the globe
+* [Zoom](/documentation/builtin_zoom.html) - enables mouse-based zooming of the globe via the mousewheel
+* [Drag](/documentation/builtin_drag.html) - enables mouse-based rotation of the globe via dragging
