+Why we don't support IE 8
+-------------------------
+
+We've been living in 2007 for a while now, pretending that new browser features didn't
+exist because they aren't in IE8.  You might not even know about some of these features,
+or think they are only enabled by jQuery or underscore, simply because it hasen't
+been an option to rely upon them.
+
+Here is the list of features you don't have if you choose to support IE 8:
+
+- HTML5 audio and video
+- SVG
+- Canvas
+- TrueType fonts
+- Media Queries
+- CSS Transforms
+- Multiple Backgrounds
+- CSS3 Units (vh, vw, rem)
+- Custom DOM events
+- Hardware accelerated graphics
+- The DOMContentLoaded event
+- addEventListener
+- Object.create, .seal, .freeze, .defineProperty
+- Array.isArray, .indexOf, .every, .some, .forEach, .map, .filter, .reduce
+- A modern javascript engine
+- A real developer tools
+- A consistent box model
+- jQuery 2
+- Google Apps
+- Tether
+
+It's true that IE 8 still holds a big chunk of the browsing population, but the reasons
+why they can't update dre dwinding.  There are two big reasons for continuing IE 8 support.
+
+#### Enterprises
+
+  Microsoft is dropping support for XP in April, organizations who want security updates will have to upgrade.
+
+#### China uses XP
+
+  Chrome, Firefox and Opera all support XP.  Nothing prevents users from upgrading, except the inertia of
+  organizations who still support IE 8.
+
+#### The Future
+
+We are skating towards where the puck will be, and we hope that as you decide to drop IE 8 support,
+you choose to add Tether to the list of awesome things you can do.
