+Polygon AggLayer is a web service that receives zero-knowledge proofs from different CDK chains and checks their soundness before sending the proof to L1 for verification.
+
+!!! important
+    Polygon manages the AggLayer in production at the current time.
+
+!!! warning
+    - The AggLayer is in development and subject to architectural changes.
+    - The code is still being audited.
+
+## Configure the AggLayer
+
+To configure the AggLayer to integrate with external CDK chains, each one requires an RPC node configuration.
+
+Add the chain configurations to the `../agglayer/docker/data/agglayer.toml` file by amending the following details to add the required chain(s).
+
+* Configure `[FullNodeRPCs]` to point to the corresponding L2 full node.
+* Configure `[L1]` to point to the corresponding L1 chain.
+* Configure the `[DB]` section with the managed database details.
+
+## Run a local AggLayer
+
+The following instructions are for users who may like to test and run a local installation of the AggLayer for research purposes.
+
+### Prerequisites
+
+Make sure you have the following software installations.
+
+- [Docker](https://docs.docker.com/engine/install/)
+- [Docker Compose](https://docs.docker.com/compose/install/)
+- [Golang](https://go.dev/doc/install)
+- [GCloud cli](https://cloud.google.com/sdk/docs/install) - production only.
+
+### Clone the repo.
+
+```sh
+git clone https://github.com/0xPolygon/agglayer.git
+cd agglayer/
+```
+
+### Set up and installation
+
+Run the following command to bring up a zkEVM node, a prover, and a mock L1 network.
+
+```sh
