+Summary:Communicate instantly via e-mail
+Description:
+Delta Chat is a project that aims to create a messaging app that is completely
+compatible to the existing e-mail infrastructure.
+
+So, with Delta Chat you get the ease of well-known messengers with the reach of
+e-mail. Moreover, you're independent from other companies or services -- as your
+data are not related to Delta Chat, you won't even add new dependecies here.
+
+Some features at a glance:
+
+* Fast by the use of Push-IMAP
+* Largest userbase -- receivers not using Delta Chat can be reached as well
+* Compatible -- not only to itself
+* Elegant and simple user interface
+* Distributed system
+* No Spam -- only messages of known users are shown by default
+* Reliable -- safe for professional use
+* Trustworthy -- can even be used for business messages
+* Fully OpenSource and Standards based
+.
