+                is a Telegram bridge that supports bridging channels/supergroups to Matrix. This can be
+                done through a "relay bot" (all Matrix users are represented through a single bot in Telegram)
+                or by making use of a user's real Telegram account (known as "puppeting"). Currently
+                only one Telegram bridge can be configured at a time.
+            </p>
