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 other mautrix bridges
You may wish to look at `roles/matrix-bridge-beeper-linkedin/templates/config.yaml.j2` to find other things you would like to configure.
## Set up Double Puppeting
If you'd like to use [Double Puppeting](https://docs.mau.fi/bridges/general/double-puppeting.html) (hint: you most likely do), you have 2 ways of going about it.
### Method 1: automatically, by enabling Shared Secret Auth
The bridge will automatically perform Double Puppeting if you enable [Shared Secret Auth](configuring-playbook-shared-secret-auth.md) for this playbook.
This is the recommended way of setting up Double Puppeting, as it's easier to accomplish, works for all your users automatically, and has less of a chance of breaking in the future.
## Usage
You then need to start a chat with `@linkedinbot:YOUR_DOMAIN` (where `YOUR_DOMAIN` is your base domain, not the `matrix.` domain).
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.
