+Let's run Craft CMS in a high-available AWS infrastructure with Cloudfront, S3, Loadbalancer, Auto Scaling, ElastcCache, RDS and much more.
 
 ## Background
 
-[...]
+If you want to run Craft CMS the way the AWS infrastructure enables you to, you'll quickly face some difficulties.
+
+This plugin solves some of the worst challanges runnning Craft CMS 3 with Cloudfront, ALB and Auto Scaling.
+
+These challenges are:
+* Storing and distribution of the **control panel resources** through a bucket without the use of a shared file system (like EFS for example).
+* Storing and distribution of **thumbnails** through a bucket. This avoids that every thumbnail is recreated on every instance.
+* Detection of Cloudfront-Requests and using the included **device detection** to replace the Craft CMS function isMobileBrowser() (which does not work behind Cloudfront anymore).
+
+The wiki also gives you some help with sample configurations and tips for the most important questions about running Craft CMS in an AWS environment.
+
+Everybody who would like to contribute their experience and know-how is welcome.
