+# Node.js GitHub sponsors
+
+The project has enabled GitHub sponsors in order to to accept
+sponsorships. Currently there is only a single one time tier which is
+called "sponsor" and one monthly tier which is called "monthly-sponsor"
+with no specific rewards.
+
+The funds are to be used for specific efforts as decided by the TSC and
+documented on this page.
+
+## Account details
+
+The account is manged by the TSC. The user id and password
+are shared with TSC members through 1password. All payments for
+sponsorships received will be made to the OpenJS Foundation who has
+agreed to manage the funds that are received on behalf of the project.
+
+## Disbursements - management
+
+Potential disbursements will be agreed through TSC discussion
+and before approval, documented in a PR in the
+[TSC repository](https://github.com/nodejs/TSC) which adds
+the intended use and funding envelope to this page. The disbursement
+is considered approved if there's no objections from a project member in 72 hours,
+and consensus has been reached in the TSC. Objections can be overridden with a TSC vote.
+
+When work is complete for an approved disbursement, a request will be
+made by the TSC to the OpenJS foundation to pay the person chosen by
+the TSC to do the work.
