+
+Docker Compose for geth-prysm
+
+## Usage
+
+Pre-requisite is to create a shared `jwt.hex` under `./shared-data` and download the `genesis.ssz` to the same directory:
+
+```bash
+mkdir -p ./shared-data
+openssl rand -hex 32 | tr -d "\n" > ./shared-data/jwt.hex
+curl -sL --output ./shared-data/genesis.ssz https://github.com/eth-clients/merge-testnets/raw/main/sepolia/genesis.ssz
+```
+
+Then start the containers:
+
+```bash
+make up
+```
+
+## Containers
+
+| Name         | Description     | Port  |
+| :----------- | :-------------: | ----: |
+| geth         | rpc port        | 8545  |
+| prysm        | rpc port        | 4000  |
