+
+## Join us for our first authentik hackathon!
+
+Everyone welcome; we will work on code, docs, and anything else that looks interesting and challenging.
+
+Moderators will be available for most US and European hours, so if during the multi-day event, participants have questions or a PR needs a technical review, we are here for you.
+
+> More details will be added soon about the exact daily timeframes, for both European-based and US-based participants.
+
+Swag? Why, Yes! From cool authentik-branded socks to food certificates, and indoubtibly GitHub fame, we've got you covered.
+
+## Date
+
+July 26-30, 2023
+
+## Where
+
+Online, in our [GitHub repo](https://github.com/goauthentik/authentik), using [Discord](https://discord.com/channels/809154715984199690/1110948434552299673) for conversations, questions, and video calls.
+
+## Registration form
+
+Use the [Hackathon 2023 Registration Form](https://docs.google.com/forms/d/e/1FAIpQLSc10MiK4li-SIY8SidhwFEwFbDcna-fio1xFY2nmimqXPPvLA/viewform) to let us know that you'll join us!
+
+> If you know what you and/or your team want to work on, you can open an [Issue](https://github.com/goauthentik/authentik/issues) using our template for all hackathon Issues at any time (why not now?) and add the `hackathon` label. Then, when you register, enter the Issue number that you opened on your registration form. This way, on Kickoff Day we can easily match particpants with their Issue of interest.
+
