 ## MultiCompiler
 
-?> Can create child compilers?
+This module, MultiCompiler, allows webpack to run multiple configurations in separate compiler.
+If the `options` parameter in the webpack's NodeJS api is an array of options, webpack applies separate compilers and calls the `callback` method at the end of each compiler execution.
+
+```javascript
+var webpack = require('webpack');
+
+var config1 = {
+  entry: './index1.js',
+  output: {filename: 'bundle1.js'}
+}
+var config2 = {
+  entry: './index2.js',
+  output: {filename:'bundle2.js'}
+}
+
+webpack([config1, config2], (err, stats) => {
+  process.stdout.write(stats.toString() + "\n");
+})

 * `plugin(name:string, handler:function)` - This allows a custom plugin to register into a **Tapable instance**'s event.
 This acts as the same as `on()` of `EventEmitter`, for registering a handler/listener to do something when the signal/event happens.
 
-* `apply(...pluginInstances: (AnyPlugin|function)[])` - `AnyPlugin` should be subclass of [AbstractPlugin](https://github.com/webpack/webpack/blob/master/lib/AbstractPlugin.js), or a class (or object, rare case) has an `apply` method, or just a function with some registration code inside.

 This method is just to **apply** plugins' definition, so that the real event listeners can be registered into the **Tapable instance**'s registry.

 These group of method act like `emit()` of `EventEmitter`, to control the event emission meticulously with various strategy for various use cases.
 
 * `mixin(pt: Object)` - a simple method to extend `Tapable`'s prototype as a mixin rather than inheritance.
