The playbook can install and configure mx-puppet-slack for you.
See the project page to learn what it does and why it might be useful to you.
To enable the Slack bridge just use the following playbook configuration:
matrix_mx_puppet_slack_enabled: true
matrix_mx_puppet_slack_client_id: ""
matrix_mx_puppet_slack_client_secret: ""Once the bot is enabled you need to start a chat with Slack Puppet Bridge with
the handle @_slackpuppet_bot:YOUR_DOMAIN (where YOUR_DOMAIN is your base
domain, not the matrix. domain).
Three authentication methods are available, Legacy Token, OAuth and xoxc token. See mx-puppet-slack documentation for more information about how to configure the bridge.
Once logged in, send list to the bot user to list the available rooms.
Clicking rooms in the list will result in you receiving an invitation to the bridged room.
Also send help to the bot to see the commands available.
