 Friendika Installation
 
+We've tried very hard to ensure that Friendika will run on commodity hosting 
+platforms - such as those used to host Wordpress blogs and Drupal websites. 
+But be aware that Friendika is more than a simple web application. It is a 
+complex communications system which more closely resembles an email server 
+than a web server. For reliability and performance, messages are delivered in
+the background and are queued for later delivery when sites are down. This
+kind of functionality requires a bit more of the host system than the typical
+blog. Not every PHP/MySQL hosting provider will be able to support Friendika. 
+Many will. But please review the requirements and confirm these with your 
+hosting provider prior to installation.
