Explain This Meta Tag from a Bootstrap Example

[Accelerator]

Hi Guys

Please could someone explain the meaning of this meta tag:

<meta http-equiv="X-UA-Compatible" content="IE=edge">

I found it in a worked example template for Bootstrap and I'd like to know what its purpose is.

Thanks

It triggers "compatibility mode" in Internet Explorer:

Use the ... value to display the webpage in EdgeHTML mode, which is the highest standards mode supported by Internet Explorer, from Internet Explorer 6 through IE11. Note that this is functionally equivalent to using the HTML5 doctype. It places Internet Explorer into the highest supported document mode. Edge most is most useful for regularly maintained websites that are routinely tested for interoperability between multiple browsers, including Internet Explorer.
