 # Web builds
 In addition to your usual Node applications, discord.js has special distributions available that are capable of running in web browsers.
 This is useful for client-side web apps that need to interact with the Discord API.
-[Webpack 2](https://webpack.js.org/) is used to build these.
+[Webpack 3](https://webpack.js.org/) is used to build these.
 
-## Usage
+## Restrictions
+- Any voice-related functionality is unavailable, as there is currently no audio encoding/decoding capabilities without external native libraries,
+  which web browsers do not support.
+- The ShardingManager cannot be used, since it relies on being able to spawn child processes for shards.
+- None of the native optional packages are usable.
+
+### Require Library
+If you are making your own webpack project, you can require `discord.js/browser` wherever you need to use discord.js, like so:
+```js
+const Discord = require('discord.js/browser');
+// do something with Discord like you normally would
+```
+
+### Webpack File
 You can obtain your desired version of discord.js' web build from the [webpack branch](https://github.com/hydrabolt/discord.js/tree/webpack) of the GitHub repository.
 There is a file for each branch and version of the library, and the ones ending in `.min.js` are minified to substantially reduce the size of the source code.

 Rather than importing discord.js with `require('discord.js')`, the entire `Discord` object is available as a global (on the `window`) object.
 The usage of the API isn't any different from using it in Node.js.
