+# SVG for Everybody
+
+[SVG for Everybody] is a script that adds [external spritemaps] support to otherwise [SVG-capable browsers].
+
+To use **svg4everybody**, include the script in your document.
+
+```html
+
+```
+
+To support IE6-8 as well, include the legacy script instead.
+
+```html
+
+```
+
+The IE6-8 script needs to be included in the `` in order to shiv the **svg** and **use** elements.
+
+If running the standard script in IE9-11, be sure to set [X-UA-Compatible] higher than IE8. This can be done with a response header or the following meta tag.
+
+```html
+
+```
+
+## Usage
+
+**spritemap.svg:**
+```html
+
+```
+
+This spritemap works fine in **Chrome**, **Firefox**, and **Opera**. [SVG for Everybody] polyfills the experience in **IE9-11**.
+
+```html
+
+
+
+```
+
+
+
+Older browsers falls back to PNG images.
+
+```html
+
+
+
+```
+
+Fallback PNGs point to the same location as their corresponding SVGs, only with the `#` hash replaced by a `.` dot, and with an appended `.png` extension.
+
+## Readability and accessibility
+
+Within your spritemap, each sprite may use a `` element to identify itself.
+
+```html
+<symbol id="codepen"><title>CodePen
+```
+
+When this sprite is used, its title will be read aloud in [JAWS](http://www.freedomscientific.com/products/fs/JAWS-product-page.asp) and [NVDA](http://www.nvaccess.org/). Then, within your document, each sprite may use a `title` attribute to identify itself.
+
+```html
+
+```
+
+This title will be read aloud in [VoiceOver](http://www.apple.com/accessibility/osx/voiceover/) and [NVDA](http://www.nvaccess.org/). At present, the `title` attribute is the only way to properly read aloud an SVG in VoiceOver.
+
+For maximum compatibility, both the `title` attribute in the document and the `title` element in the SVG should be used.
+
+ARIA roles may be used to provide even more accessibility. `role="presentation"` should be used when a sprite decorates other content.
+
+```html
+ Find me on Twitter
+```
+
+Alternatively, `role="img"` should be used when a sprite necessitates its own description.
+
+```html
+
+```

+
+## Smaller SVGs
+
+SVG files, especially exported from various editors, usually contains a lot of redundant and useless information such as editor metadata, comments, hidden elements, default or non-optimal values and other stuff that can be safely removed or converted without affecting SVG rendering result.
+
+Use a tool like [SVGO](https://github.com/svg/svgo) to optimize SVG spritemaps.
+
+```sh
+$ [sudo] npm install -g svgo
+$ svgo spritemap.svg
