+========
+Tidelift
+========
+
+pluggy is a member of `Tidelift`_. This document describes how the core team manages
+Tidelift-related activities.
+
+What is it
+==========
+
+Tidelift aims to make Open Source sustainable by offering subscriptions to companies which rely
+on Open Source packages. This subscription allows it to pay maintainers of those Open Source
+packages to aid sustainability of the work.
+
+It is the perfect platform for companies that want to support Open Source packages and at the same
+time obtain assurances regarding maintenance, quality and security.
+
+Funds
+=====
+
+It was decided in the `mailing list`_ that the Tidelift contribution will be split evenly between
+members of the `contributors team`_ interested in receiving funding.
+
+The current list of contributors receiving funding are:
+
+* `@nicoddemus`_
+* `@The-Compiler`_
+* `@RonnyPfannschmidt`_
+
+Contributors interested in receiving a part of the funds just need to submit a PR adding their
+name to the list. Contributors that want to stop receiving the funds should also submit a PR
+in the same way.
+
+The PR should mention `@pytest-dev/tidelift-admins`_ so appropriate changes
+can be made in the Tidelift platform.
+
+After the PR has been accepted and merged, the contributor should register in the `Tidelift`_
+platform and follow the instructions there, including signing an `agreement`_.
+
+Admins
+======
+
+A few people have admin access to the Tidelift dashboard to make changes. Those people
+are part of the `@pytest-dev/tidelift-admins`_ team.
+
+`Core contributors`_ interested in helping out with Tidelift maintenance are welcome! We don't
+expect much work here other than the occasional adding/removal of a contributor from receiving
+funds. Just drop a line to one of the `@pytest-dev/tidelift-admins`_ or use the mailing list.
