+
+## Installing Bootstrap
+
+[Install bootstrap]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/download/#npm) as a Node.js module using npm.
+
+## Importing JavaScript
+
+Import [Bootstrap's JavaScript]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/) by adding this line to your app's entry point (usually `index.js` or `app.js`):
+
+{% highlight js %}
+import 'bootstrap';
+{% endhighlight %}
+
+Alternatively, you may **import plugins individually** as needed:
+
+{% highlight js %}
+import 'bootstrap/js/dist/util';
+import 'bootstrap/js/dist/dropdown';
+...
+{% endhighlight %}
+
+Bootstrap is dependent on [jQuery](https://jquery.com/) and [Popper](https://popper.js.org/),
+these are defined as `peerDependencies`, this means that you will have to make sure to add both of them
+to your `package.json` using `npm install --save jquery popper.js`.
+
+{% callout warning %}
+Notice that if you chose to **import plugins individually**, you must also install [exports-loader](https://github.com/webpack-contrib/exports-loader)
+{% endcallout %}
+
+## Importing Styles
+
+### Importing Precompiled Sass
+
+To enjoy the full potential of Bootstrap and customize it to your needs, use the source files as a part of your project's bundling process.
+
+First, create your own `_custom.scss` and use it to override the [built-in custom variables]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/options/). Then, use your main sass file to import your custom variables, followed by Bootstrap:
+
+{% highlight scss %}
+@import "custom";
+@import "~bootstrap/scss/bootstrap";
+{% endhighlight %}
+
+For Bootstrap to compile, make sure you install and use the required loaders: [sass-loader](https://github.com/webpack-contrib/sass-loader), [postcss-loader](https://github.com/postcss/postcss-loader) with [Autoprefixer](https://github.com/postcss/autoprefixer#webpack). With minimal setup, your webpack config should include this rule or similar:
+
+{% highlight js %}
+  ...
+  {
+    test: /\.(scss)$/,
+    use: [{
+      loader: 'style-loader', // inject CSS to page
+    }, {
+      loader: 'css-loader', // translates CSS into CommonJS modules
+    }, {
+      loader: 'postcss-loader', // Run post css actions
+      options: {
+        plugins: function () { // post css plugins, can be exported to postcss.config.js
+          return [
+            require('precss'),
+            require('autoprefixer')
+          ];
+        }
+      }
+    }, {
+      loader: 'sass-loader' // compiles Sass to CSS
+    }]
+  },
+  ...
+{% endhighlight %}
+
+### Importing Compiled CSS
+
+Alternatively, you may use Bootstrap's ready-to-use css by simply adding this line to your project's entry point:
+
+{% highlight js %}
+import 'bootstrap/dist/css/bootstrap.min.css';
+{% endhighlight %}
+
+In this case you may use your existing rule for `css` without any special modifications to webpack config except you don't need `sass-loader` just [style-loader](https://github.com/webpack-contrib/style-loader) and [css-loader](https://github.com/webpack-contrib/css-loader).
+
+{% highlight js %}
+  ...
+  module: {
+    rules: [
+      {
+        test: /\.css$/,
+        use: ['style-loader', 'css-loader']
+      }
+    ]
+  }
+  ...
+{% endhighlight %}
