If you would like Mjolnir to be able to deactivate users, move aliases, shutdown rooms, etc then it must be a server admin so you need to change `admin=no` to `admin=yes` in the command above.
You will need to prevent Synapse from rate limiting the bot's account. This is not an optional step. If you do not do this step Mjolnir will crash. This can be done using Synapse's [admin API](https://matrix-org.github.io/synapse/latest/admin_api/user_admin_api.html#override-ratelimiting-for-users). Please ask for help if you are uncomfortable with these steps or run into issues.
If your Synapse Admin API is exposed to the internet for some reason like running the Synapse Admin Role [Link](configuring-playbook-synapse-admin.md) or running `matrix_synapse_container_labels_public_client_synapse_admin_api_enabled: true` in your playbook config. If your API is not externally exposed you should still be able to on the local host for your synapse run these commands.
The following command works on semi up to date Windows 10 installs and All Windows 11 installations and other systems that ship curl. `curl --header "Authorization: Bearer <access_token>" -X POST https://matrix.example.com/_synapse/admin/v1/users/@example:example.com/override_ratelimit` Replace `@example:example.com` with the MXID of your Mjolnir and example.com with your homeserver domain. You can easily obtain an access token for a homeserver admin account the same way you can obtain an access token for Mjolnir itself. If you made Mjolnir Admin you can just use the Mjolnir token.
Using your own account, create a new invite only room that you will use to manage the bot. This is the room where you will see the status of the bot and where you will send commands to the bot, such as the command to ban a user from another room. Anyone in this room can control the bot so it is important that you only invite trusted users to this room.
If you make the management room encrypted (E2EE), then you MUST enable and use Pantalaimon (see below).
Once you have created the room you need to copy the room ID so you can tell the bot to use that room. In Element Web you can do this by going to the room's settings, clicking Advanced, and then copying the internal room ID. The room ID will look something like `!qporfwt:example.com`.
Decide whether you want Mjolnir to be capable of operating in end-to-end encrypted (E2EE) rooms. This includes the management room and the moderated rooms. To support E2EE, Mjolnir needs to [use Pantalaimon](configuring-playbook-pantalaimon.md).
### 5a. Configuration with E2EE support
When using Pantalaimon, Mjolnir will log in to its bot account itself through Pantalaimon, so configure its username and password.
The playbook's `group_vars` will configure other required settings. If using this role separately without the playbook, you also need to configure the two URLs that Mjolnir uses to reach the homeserver, one through Pantalaimon and one "raw". This example is taken from the playbook's `group_vars`:
<!-- NOTE: let this conservative command run (instead of install-all) to make it clear that failure of the command means something is clearly broken. -->
- The `ensure-matrix-users-created` playbook tag makes the playbook automatically create the bot's user account.
- The shortcut commands with `just` program are also available: `just install-all` or `just setup-all`
`just install-all` is useful for maintaining your setup quickly 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. For more information about `just` shortcuts, take a look at this page: [Running `just` commands](just.md)
- If you change the Pantalaimon's password (`matrix_bot_mjolnir_pantalaimon_password` in your `vars.yml` file) subsequently, its credentials on the homeserver won't be updated automatically. If you'd like to change the password, use a tool like [synapse-admin](configuring-playbook-synapse-admin.md) to change it, and then update `matrix_bot_mjolnir_pantalaimon_password` to let Pantalaimon know its new password.
You can refer to the upstream [documentation](https://github.com/matrix-org/mjolnir) for additional ways to use and configure Mjolnir. Check out their [quickstart guide](https://github.com/matrix-org/mjolnir#quickstart-guide) for some basic commands you can give to the bot.
You can configure additional options by adding the `matrix_bot_mjolnir_configuration_extension_yaml` variable to your `inventory/host_vars/matrix.example.com/vars.yml` file.
