# Advanced settings

Advanced settings are per-task configuration options beyond the task's code and user-facing options. They control how the task is documented, how its code is executed, and how its actions are performed.

* [Documentation](https://learn.mechanic.dev/core/tasks/advanced-settings/documentation) — add Markdown documentation that is displayed to users alongside the task
* [JavaScript](https://learn.mechanic.dev/core/tasks/advanced-settings/javascript) — attach JavaScript to the online storefront or order status page
* [Perform action runs in sequence](https://learn.mechanic.dev/core/tasks/advanced-settings/perform-action-runs-in-sequence) — force the task's actions to run one at a time, in order, instead of concurrently
