+
+## Install

+```js
+import throttle from 'throttleit';
+
+// Throttling a function that processes data.
+function processData(data) {
+	console.log('Processing:', data);
+
+	// Add data processing logic here.
+}
+
+// Throttle the `processData` function to be called at most once every 3 seconds.
+const throttledProcessData = throttle(processData, 3000);
+
+// Simulate calling the function multiple times with different data.
+throttledProcessData('Data 1');
+throttledProcessData('Data 2');
+throttledProcessData('Data 3');
