+### Security release stewards
+
+When possible, the commitment to take slots in the
+security release steward rotation is made by companies in order
+to ensure individuals who act as security stewards have the
+support and recognition from their employer to be able to
+prioritize security releases. Security release stewards manage security
+releases on a rotation basis as outlined in the
+[security release process](./doc/contributing/security-release-process.md).

+## Security release stewards
+
+For each security release, a security steward will take ownership for
+coordinating the steps outlined in this process. Security stewards
+are nominated through an issue in the TSC repository and approved
+through the regular TSC consensus process. Once approved, they
+are given access to all of the resources needed to carry out the
+steps listed in the process as outlined in
+[security steward on/off boarding](security-steward-on-off-boarding.md).
+
+The current security stewards are documented in the main Node.js
+[README.md](https://github.com/nodejs/node#security-release-stewards).
