-# Server-Client API
+# Start
 
-### Authorization
+The following pages document the server-client API of polyproto. Each file represents a group of 
+routes, organizing them by their purpose.
 
-**Bearer token**, unless specified otherwise.
+The core of the protocol lies in the [federation](federation.md) routes, which are used to 
+negotiate and establish connections between foreign servers and clients. 
 
-### Server
-
-`http://localhost:3001/api`
+Theoretically, the polyproto-core federation protocol can be used with a different set of chat-APIs 
+However, a full implementation of the protocol requires the use of the
+[polyproto-chat](chat/index.md) routes. There is no interoperability if different chat-APIs/protocols
+are used.
