+## License and SSA
+
+Each Gluu Flex instance needs an SSA(Software Statement Assertion) as an input 
+during the installation process. SSA, which is an encrypted JWT string, 
+represents an installed instance of the Gluu Flex. Customers can get one or 
+more SSAs issued for a particular license using [Agama Lab](https://cloud.gluu.org/agama-lab).
