+
+## Setup Ansible
+
+To get started, follow the [installation](../README.md#installation) guide to setup ansible on your machine
+
+## Setup and Run Optimism
+
+The following commands have to be executed in [`l2-setup`](./) directory
+
+- Edit [`l2-config.env.j2`](./templates/configs/l2-config.env.j2) and fill in the following values
+
+  ```bash
+  # Chain ID of the L1 chain
+  CERC_L1_CHAIN_ID=
+
+  # L1 RPC endpoint
+  CERC_L1_RPC=
+
+  # Amount to send the proposer on L2 (default: 0.2 ether)
+  CERC_L2_PROPOSER_AMOUNT=
+
+  # Amount to send the batcher on L2 (default: 0.1 ether)
+  CERC_L2_BATCHER_AMOUNT=
+
+  # L1 RPC endpoint host or IP address
+  CERC_L1_HOST=
+
+  # L1 RPC endpoint port number
+  CERC_L1_PORT=
+
+  # Address of the funded account on L1
+  # Used for optimism contracts deployment
+  CERC_L1_ADDRESS=
+
+  # Private key of the funded account on L1
+  CERC_L1_PRIV_KEY=
+  ```
+
+- To setup and run L2, execute the `run-optimism.yml` Ansible playbook by running the following command.
+
+  NOTE: By default, deployments are created in the `l2-setup/out` directory. To change this location, update the `l2_directory` variable in the [vars.yml](./vars.yml) file.
+
+  ```bash
+  LANG=en_US.utf8 ansible-playbook -i localhost, --connection=local run-optimism.yml --extra-vars='{ "target_host": "localhost"}' --user $USER
+  ```
+
+  - For skipping container build, set `"skip_container_build" : true` in the `--extra-vars` parameter:
+
+    ```bash
+    LANG=en_US.utf8 ansible-playbook -i localhost, --connection=local run-optimism.yml --extra-vars='{"target_host" : "localhost", "skip_container_build": true}' -kK --user $USER
+    ```
