# Technical bulletins

Technical bulletins are safety and service notices you publish to a customer's portal, such as a seal replacement advisory or a recall notice. Use this section to create bulletins and to review or remove the ones already published.

* [Create a technical bulletin](/customers/technical-bulletins/create-a-technical-bulletin.md): Write a bulletin, set its severity, attach a file, and choose which facilities it applies to.
* [Review and remove bulletins](/customers/technical-bulletins/review-and-remove-bulletins.md): See the bulletins published to a customer and delete ones that are no longer needed.
