	<h2>Overview</h2>
	<div>
		<p>
			Three.js can use WebGL to render your scenes on all modern browsers. For older browsers, especially Internet Explorer 10 and below, you may have to fallback to one of the other [link:https://github.com/mrdoob/three.js/tree/master/examples/jsm/renderers renderers] (CSS2DRenderer, CSS3DRenderer, SVGRenderer). Additionally, you may have to include some polyfills, especially if you are using files from the [link:https://github.com/mrdoob/three.js/tree/master/examples /examples] folder.
		</p>
		<p>
			Note: if you don't need to support these old browsers, then it is not recommended to use the other renderers as they are slower and support less features than the WebGLRenderer.
		</p>
	</div>

	<h2>Browsers that support WebGL</h2>
	<div>
		<p>
			Google Chrome 9+, Firefox 4+, Opera 15+, Safari 5.1+, Internet Explorer 11 and Microsoft Edge. You can find which browsers support WebGL at [link:https://caniuse.com/#feat=webgl Can I use WebGL].

	</div>

	<h2>Polyfills</h2>
	<div>
		<p>Just import polyfills based on your requirements. Taking IE9 as an example, you need to polyfill at least these features:</p>
