+# Setting up Hookshot (optional)
+
+The playbook can install and configure [matrix-hookshot](https://github.com/Half-Shot/matrix-hookshot) for you.
+
+See the project's [documentation](https://half-shot.github.io/matrix-hookshot/hookshot.html) to learn what it does and why it might be useful to you.
+
+
+## Setup Instructions
+
+Refer to the [official instructions](https://half-shot.github.io/matrix-hookshot/setup.html) to learn what the individual options do.
+
+1. For each of the services (GitHub, GitLab, JIRA, generic webhooks) fill in the respected variables `matrix_hookshot_service_*` listed in [main.yml](roles/matrix-bridge-hookshot/defaults/main.yml) as required.
+2. If you've already installed Matrix services using the playbook before, you'll need to re-run it (`--tags=setup-all,start`). If not, proceed with [configuring other playbook services](configuring-playbook.md) and then with [Installing](installing.md). Get back to this guide once ready.
+3. Refer to the [official instructions](https://half-shot.github.io/matrix-hookshot/usage.html) to start bridging things.
+
+Other configuration options are available via the `matrix_hookshot_configuration_extension_yaml` variable.
