+### How it works
+
+When callbacks outside of Mithril run, you need to notify Mithril's rendering engine that a redraw is needed. External callbacks could be `setTimeout`/`setInterval`/`requestAnimationFrame` callbacks, web socket library callbacks, event handlers in jQuery plugins, third party XHR request callbacks, etc.
+
+To trigger a redraw, call `m.redraw()`
+
+You should not call m.redraw from a [lifecycle method](lifecycle-methods.md). Doing so will result in undefined behavior.
