+
+Through exposing a small web server, the webhooks bridge is able to interpret Slack webhooks and post them to designated rooms in Matrix. Additional fields are present for a more matrix-feeling message, if desired. Future plans include outgoing webhooks to notify external services of particular events in rooms.
+
+The source (and more information) can be found on [GitHub](https://github.com/turt2live/matrix-appservice-webhooks).
