-Changes from D3 3.x:
+## Installing
 
-* Timer callbacks are now passed the current time as a second argument, in addition to the elapsed time; this is useful for precise scheduling of secondary timers.
+If you use NPM, `npm install d3-timer`. Otherwise, download the [latest release](https://github.com/d3/d3-timer/releases/latest).
 
-* A new [timerReplace](#timerReplace) method has been added to replace the current timer within a timer callback.
+## API Reference
 
-* The timer.flush method has been renamed [timerFlush](#timerFlush). This method now accepts an optional *time* argument representing the current time, and returns the time of the earliest next timer. Calling this method within a timer callback no longer causes a crash.
-
-* Calling [timer](#timer) within a timer callback no longer makes a duplicate requestAnimationFrame. Calling this method with a delay greater than 24ms when no earlier timers are active guarantees a setTimeout rather than a requestAnimationFrame.
