+    longDescription = ''
+      As an all-in-one moderation tool, it can protect your server from
+      malicious invites, spam messages, and whatever else you don't want.
+      In addition to server-level protection, Mjolnir is great for communities
+      wanting to protect their rooms without having to use their personal
+      accounts for moderation.
+
+      The bot by default includes support for bans, redactions, anti-spam,
+      server ACLs, room directory changes, room alias transfers, account
+      deactivation, room shutdown, and more.
+
+      A Synapse module is also available to apply the same rulesets the bot
+      uses across an entire homeserver.
