+## Where are the docs?
+
+_This repository is still young & early._
+
+It is the result of a research spike conducted by the Core [Pocket Network](https://pokt.network/) Protocol Team at [GROVE](https://grove.city/) documented [here](https://www.pokt.network/why-pokt-network-is-rolling-with-rollkit-a-technical-deep-dive/) (deep dive) and [here](https://www.pokt.network/a-sovereign-rollup-and-a-modular-future/) (summary).
+
+For now, we recommend visiting the links in [pokt-network/pocket/README.md](https://github.com/pokt-network/pocket/blob/main/README.md) as a starting point.
+
+If you want to contribute to this repository at this stage, you know where to find us.
