The playbook can install and configure [beeper-linkedin](https://github.com/beeper/linkedin) for you, for bridging to [LinkedIn](https://www.linkedin.com/) Messaging. This bridge is based on the mautrix-python framework and can be configured in a similar way to the mautrix bridges.
### Enable Appservice Double Puppet or Shared Secret Auth (optional)
If you want to set up [Double Puppeting](https://docs.mau.fi/bridges/general/double-puppeting.html) (hint: you most likely do) for this bridge automatically, you need to have enabled [Appservice Double Puppet](configuring-playbook-appservice-double-puppet.md) or [Shared Secret Auth](configuring-playbook-shared-secret-auth.md) service for this playbook.
See [this section](configuring-playbook-bridge-mautrix-bridges.md#set-up-double-puppeting-optional) on the [common guide for configuring mautrix bridges](configuring-playbook-bridge-mautrix-bridges.md) for details about setting up Double Puppeting.
**Note**: double puppeting with the Shared Secret Auth works at the time of writing, but is deprecated and will stop working in the future.
See [this section](configuring-playbook-bridge-mautrix-bridges.md#extending-the-configuration) on the [common guide for configuring mautrix bridges](configuring-playbook-bridge-mautrix-bridges.md) for details about variables that you can customize and the bridge's default configuration, including [bridge permissions](configuring-playbook-bridge-mautrix-bridges.md#configure-bridge-permissions-optional), [encryption support](configuring-playbook-bridge-mautrix-bridges.md#enable-encryption-optional), [relay mode](configuring-playbook-bridge-mautrix-bridges.md#enable-relay-mode-optional), [bot's username](configuring-playbook-bridge-mautrix-bridges.md#setting-the-bot-s-username-optional), etc.
**Note**: when following the guide to configure the bridge, make sure to replace `_mautrix_SERVICENAME_` in the variable names with `_beeper_linkedin_`.
After configuring the playbook, run it with [playbook tags](playbook-tags.md) as below:
<!-- NOTE: let this conservative command run (instead of install-all) to make it clear that failure of the command means something is clearly broken. -->
`just install-all` is useful for maintaining your setup quickly ([2x-5x faster](../CHANGELOG.md#2x-5x-performance-improvements-in-playbook-runtime) than `just setup-all`) when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed.
If you don't have 2FA enabled and are logging in from a strange IP for the first time, LinkedIn will send an email with a one-time code. You can use this code to authorize the bridge session. In my experience, once the IP is authorized, you will not be asked again.
