 # Interoperable Private Attribution (IPA)
 
-IPA is a Private Measurement proposal for the PATCG.
+IPA is a [Private Measurement proposal](https://github.com/patcg/private-measurement) for the W3C's [Private Advertising Technology Community Group (PATCG.)](https://github.com/patcg/).
 
-[IPA End to End](IPA-End-to-End.md) is our latest version of the proposal. Our original draft, published in January 2022, is [available here](https://docs.google.com/document/d/1KpdSKD8-Rn0bWPTu4UtK54ks0yv2j22pA5SrAD9av4s/edit).
+## Latest Protocol Draft
+[IPA End to End](IPA-End-to-End.md) is our latest version of the proposal.
 
-Prototype implementations of this protocol can be found [here](https://github.com/private-attribution/).
+We also have a [formal analysis posted on ePrint.](https://eprint.iacr.org/2023/437)
+
+
+
+## Implementation
+We are actively [prototyping an implementation](https://github.com/private-attribution/ipa).
+
+## Get Involved
+
+The [PATCG hosts meetings](https://github.com/patcg/meetings) on a roughly bi-monthly basis. Anyone can [sign up to join the community group](https://www.w3.org/community/patcg/) and join these meetings.
+
+The IPA team also hosts an [IPA focused bi-weekly VC call to discuss open issues and progress](https://github.com/patcg-individual-drafts/ipa/issues/47).
+
+[We also have open research questions in the issues on this repo.](https://github.com/patcg-individual-drafts/ipa/labels/research%20questions)
