+# Setting up Mautrix Twitter (optional)
+
+**Note**: bridging to [Twitter](https://twitter.com/) can also happen via the [mx-puppet-twitter](configuring-playbook-bridge-mx-puppet-twitter.md) bridge supported by the playbook.
+
+The playbook can install and configure [mautrix-twitter](https://github.com/tulir/mautrix-twitter) for you.
+
+See the project's [documentation](https://github.com/tulir/mautrix-twitter/wiki#usage) to learn what it does and why it might be useful to you.
+
+```yaml
+matrix_mautrix_twitter_enabled: true
+```
+
+
+## Set up Double Puppeting
+
+If you'd like to use [Double Puppeting](https://github.com/tulir/mautrix-twitter/wiki/Authentication#double-puppeting) (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.
+
+### Method 2: manually, by asking each user to provide a working access token
+
+This method is currently not available for the Mautrix-Twitter bridge, but is on the [roadmap](https://github.com/tulir/mautrix-twitter/blob/master/ROADMAP.md) under Misc/Manual login with `login-matrix`
+
+## Usage
+
+1. You then need to start a chat with `@twitterbot:YOUR_DOMAIN` (where `YOUR_DOMAIN` is your base domain, not the `matrix.` domain).
+2. Send login-cookie to start the login. The bot should respond with instructions on how to proceed.
+
+You can learn more here about authentication from the bridge's [official documentation on Authentication](https://docs.mau.fi/bridges/python/twitter/authentication.html).
+
+If you run into trouble, check the [Troubleshooting](#troubleshooting) section below.
+
+After successfully enabling bridging, you may wish to [set up Double Puppeting](#set-up-double-puppeting), if you haven't already done so.
