 # Cloud
 
-About the cloud services.
+At SRS, our goal is to establish a non-profit, open-source community dedicated to creating an all-in-one, 
+out-of-the-box, open-source video solution for live streaming and WebRTC online services.
+
+We also offer cloud services for those who prefer to use cloud service instead of building from scratch. 
+Please choose the cloud service that best suits your needs.
