 # Setting up Mautrix Discord bridging (optional)

 **Note**: bridging to [Discord](https://discordapp.com/) can also happen via the [mx-puppet-discord](configuring-playbook-bridge-mx-puppet-discord.md) and [matrix-appservice-discord](configuring-playbook-bridge-appservice-discord.md) bridges supported by the playbook.
 - For using as a Bot we recommend the [Appservice Discord](configuring-playbook-bridge-appservice-discord.md), because it supports plumbing.
 - For personal use with a discord account we recommend the `mautrix-discord` bridge (the one being discussed here), because it is the most fully-featured and stable of the 3 Discord bridges supported by the playbook.

 # Setting up Instagram bridging via Mautrix Meta (optional)

 The playbook can install and configure the [mautrix-meta](https://github.com/mautrix/meta) Messenger/Instagram bridge for you.
 
 Since this bridge component can bridge to both [Messenger](https://messenger.com/) and [Instagram](https://instagram.com/) and you may wish to do both at the same time, the playbook makes it available via 2 different Ansible roles (`matrix-bridge-mautrix-meta-messenger` and `matrix-bridge-mautrix-meta-instagram`). The latter is a reconfigured copy of the first one (created by `just rebuild-mautrix-meta-instagram` and `bin/rebuild-mautrix-meta-instagram.sh`).
