 ## Introduction
 
-`deposit-cli` is a tool for creating [EIP-2335 format](https://eips.ethereum.org/EIPS/eip-2335) BLS12-381 keystores and a corresponding `deposit_data*.json` file for [Ethereum Staking Launchpad](https://github.com/ethereum/staking-launchpad). One can also provide a keystore file to generate a `signed_exit_transaction*.json` file to be broadcast at a later date to exit a validator.

-#### Option 4. Use Docker image
+#### Option 4. Use published docker image
+
+##### Step 1. Pull the official docker image
+
+Run the following command to pull the latest docker image published on the Github repository:
+
+```sh
+docker pull ghcr.io/eth-educators/ethstaker-deposit-cli:latest
+```
+
+##### Step 2. Create keys and `deposit_data-*.json`
+
+Run the following command to enter the interactive CLI:
+
+```sh
+docker run -it --rm -v $(pwd)/validator_keys:/app/validator_keys ghcr.io/eth-educators/ethstaker-deposit-cli:latest
+```
+
+You can also run the tool with optional arguments:
+
+```sh
+docker run -it --rm -v $(pwd)/validator_keys:/app/validator_keys ghcr.io/eth-educators/ethstaker-deposit-cli:latest new-mnemonic --num_validators=<NUM_VALIDATORS> --mnemonic_language=english
+```
+
+Example for 1 validator on the [Holesky testnet](https://holesky.launchpad.ethereum.org/) using english:
+
+```sh
+docker run -it --rm -v $(pwd)/validator_keys:/app/validator_keys ghcr.io/eth-educators/ethstaker-deposit-cli:latest new-mnemonic --num_validators=1 --mnemonic_language=english --chain=holesky
+```
