+                    TigerChat is a simple peer-to-peer/full-mesh chat app
+                    written in Go and transpiled to JavaScript via GopherJS.
+                    Every connection is inherently encrypted by WebRTC, and
+                    every peer must successfully perform a three-way
+                    cryptographic challenge-response handshake using Argon2 with
+                    each of the other peers in order to be authenticated with
+                    each other. However, while this provides reasonable security
+                    for fun chats amongst friends, it's not intended for the
+                    transmission of highly sensitive data.
