+# Configuring continuwuity (optional)
+
+The playbook can install and configure the [continuwuity](https://continuwuity.org) Matrix server for you.
+
+See the project's [documentation](https://continuwuity.org) to learn what it does and why it might be useful to you.
+
+By default, the playbook installs [Synapse](https://github.com/element-hq/synapse) as it's the only full-featured Matrix server at the moment. If that's okay, you can skip this document.
+
+💡 **Note**: continuwuity is a fork of [conduwuit](./configuring-playbook-conduwuit.md), which the playbook also supports.
+
+> [!WARNING]
+> - **You can't switch an existing Matrix server's implementation** (e.g. Synapse -> continuwuity). Proceed below only if you're OK with losing data or you're dealing with a server on a new domain name, which hasn't participated in the Matrix federation yet.
+> - **Homeserver implementations other than Synapse may not be fully functional**. The playbook may also not assist you in an optimal way (like it does with Synapse). Make yourself familiar with the downsides before proceeding
+
+## Adjusting the playbook configuration
+
+To use continuwuity, you **generally** need to adjust the `matrix_homeserver_implementation: synapse` configuration on your `inventory/host_vars/matrix.example.com/vars.yml` file as below:
+
+```yaml
+matrix_homeserver_implementation: continuwuity
+
+# Registering users can only happen via the API,
+# so it makes sense to enable it, at least initially.
+matrix_continuwuity_config_allow_registration: true
+
+# Generate a strong registration token to protect the registration endpoint from abuse.
+# You can create one with a command like `pwgen -s 64 1`.
+matrix_continuwuity_config_registration_token: ''
+```
+
+### Extending the configuration
+
+There are some additional things you may wish to configure about the server.
+
+Take a look at:
+
+- `roles/custom/matrix-continuwuity/defaults/main.yml` for some variables that you can customize via your `vars.yml` file
+- `roles/custom/matrix-continuwuity/templates/continuwuity.toml.j2` for the server's default configuration
+
+There are various Ansible variables that control settings in the `continuwuity.toml` file.
+
+If a specific setting you'd like to change does not have a dedicated Ansible variable, you can either submit a PR to us to add it, or you can [override the setting using an environment variable](https://continuwuity.org/configuration#environment-variables) using `matrix_continuwuity_environment_variables_extension`. For example:
+
+```yaml
+matrix_continuwuity_environment_variables_extension: |
+  continuwuity_MAX_REQUEST_SIZE=50000000
+  continuwuity_REQUEST_TIMEOUT=60
+```
+
+## Creating the first user account
+
+Unlike other homeserver implementations (like Synapse and Dendrite), continuwuity does not support creating users via the command line or via the playbook.
+
+If you followed the instructions above (see [Adjusting the playbook configuration](#adjusting-the-playbook-configuration)), you should have registration enabled and protected by a registration token.
+
+This should allow you to create the first user account via any client (like [Element Web](./configuring-playbook-client-element-web.md)) which supports creating users.
+
+The **first user account that you create will be marked as an admin** and **will be automatically invited to an admin room**.
+
+
+## Configuring bridges / appservices
+
+For other homeserver implementations (like Synapse and Dendrite), the playbook automatically registers appservices (for bridges, bots, etc.) with the homeserver.
+
+For continuwuity, you will have to manually register appservices using the [`!admin appservices register` command](https://continuwuity.org/appservices.html#set-up-the-appservice---general-instructions) sent to the server bot account.
+
+The server's bot account has a Matrix ID of `@conduit:example.com` (not `@continuwuity:example.com`!) due to continuwuity's historical legacy.
+Your first user account would already have been invited to an admin room with this bot.
+
+Find the appservice file you'd like to register. This can be any `registration.yaml` file found in the `/matrix` directory, for example `/matrix/mautrix-signal/bridge/registration.yaml`.
+
+Then, send its content to the existing admin room:
+
+    !admin appservices register
+
+    ```
+    as_token: <token>
+    de.sorunome.msc2409.push_ephemeral: true
+    hs_token: <token>
+    id: signal
+    namespaces:
+      aliases:
+      - exclusive: true
+        regex: ^#signal_.+:example\.org$
+      users:
+      - exclusive: true
+        regex: ^@signal_.+:example\.org$
+      - exclusive: true
+        regex: ^@signalbot:example\.org$
+    rate_limited: false
+    sender_localpart: _bot_signalbot
+    url: http://matrix-mautrix-signal:29328
+    ```
+
+## Migrating from conduwuit
+
+Since continuwuity is a drop-in replacement for conduwuit, migration is possible. First, make sure that continuwuity is properly set up on your `vars.yml` and run the tag `just run-tags migrate-conduwuit`
+
+## Troubleshooting
+
+As with all other services, you can find the logs in [systemd-journald](https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html) by logging in to the server with SSH and running `journalctl -fu matrix-continuwuity`.
