 Why an Open Guide?
 ------------------
 
-A lot of information on AWS is already written. Most people learn AWS by reading a blog or a “[getting started guide](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EC2_GetStarted.html)” and referring to the [standard AWS references](https://aws.amazon.com/documentation/). Nonetheless, trustworthy and practical information and recommendations aren’t easy to come by. AWS’s own documentation is a great but sprawling resource few have time time to read fully, and it doesn’t include anything but official facts, so omits experiences of engineers. The information in blogs or [Stack Overflow](http://stackoverflow.com/questions/tagged/amazon-web-services) is also not consistently up to date.

 This guide is by and for engineers who use AWS. It aims to be a useful, living reference that consolidates links, tips, gotchas, and best practices. It arose from discussion and editing over beers by [several engineers](AUTHORS.md) who have used AWS extensively.
