 2. For each of the services (GitHub, GitLab, Jira, Figma, generic webhooks) fill in the respective variables `matrix_hookshot_service_*` listed in [main.yml](/roles/custom/matrix-bridge-hookshot/defaults/main.yml) as required.

If not, proceed with [configuring other playbook services](configuring-playbook.md) and then with [Installing](installing.md). Get back to this guide once ready. Hookshot can be set up individually using the tag `setup-hookshot`.
 
 Other configuration options are available via the `matrix_hookshot_configuration_extension_yaml` and `matrix_hookshot_registration_extension_yaml` variables, see the comments in [main.yml](/roles/custom/matrix-bridge-hookshot/defaults/main.yml) for how to use them.

 The GitHub bridge requires you to install a private key file. This can be done in multiple ways:
 - copy the *contents* of the downloaded file and set the variable `matrix_hookshot_github_private_key` to the contents (see example in [main.yml](/roles/custom/matrix-bridge-hookshot/defaults/main.yml)).
 - somehow copy the file to the path `{{ matrix_hookshot_base_path }}/{{ matrix_hookshot_github_private_key_file }}` (default: `/matrix/hookshot/private-key.pem`) on the server manually.
-- use the `matrix-aux` role to copy the file from an arbitrary path on your ansible client to the correct path on the server.
+- use the [`aux` role](https://github.com/mother-of-all-self-hosting/ansible-role-aux) to copy the file from an arbitrary path on your ansible client to the correct path on the server.
