+OpenCollective
+==============
+
+pytest has a collective setup at `OpenCollective`_. This document describes how the core team manages
+OpenCollective-related activities.
+
+What is it
+==========
+
+Open Collective is an online funding platform for open and transparent communities.
+It provide tools to raise money and share your finances in full transparency.
+
+It is the platform of choice for individuals and companies that want to make one-time or
+monthly donations directly to the project.
+
+Funds
+=====
+
+The OpenCollective funds donated to pytest will be used to fund overall maintenance,
+local sprints, merchandising (stickers to distribute in conferences for example), and future
+gatherings of pytest developers (Sprints).
+
+`Core contributors`_ which are contributing on a continuous basis are free to submit invoices
+to bill maintenance hours using the platform. How much each contributor should request is still an
+open question, but we should use common sense and trust in the contributors, most of which know
+themselves in-person. A good rule of thumb is to bill the same amount as monthly payments
+contributors which participate in the `Tidelift`_ subscription. If in doubt, just ask.
+
+Admins
+======
+
+A few people have admin access to the OpenCollective dashboard to make changes. Those people
+are part of the `@pytest-dev/opencollective-admins`_ team.
+
+`Core contributors`_ interested in helping out with OpenCollective maintenance are welcome! We don't
+expect much work here other than the occasional approval of expenses from other core contributors.
+Just drop a line to one of the `@pytest-dev/opencollective-admins`_ or use the mailing list.

+Sponsor
+=======
+
+pytest is maintained by a team of volunteers from all around the world in their free time. While
+we work on pytest because we love the project and use it daily at our daily jobs, monetary
+compensation when possible is welcome to justify time away from friends, family and personal time.
+
+Money is also used to fund local sprints, merchandising (stickers to distribute in conferences for example)
+and every few years a large sprint involving all members.
+
+If you or your company benefit from pytest and would like to contribute to the project financially,
+we are members of two online donation platforms to better suit your needs.
+
+Tidelift
+--------
+
+`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.

+You can help pytest and the ecosystem by obtaining a `Tidelift subscription`_.
