+# l2-setup
+
+## 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-vars.yml`](./l2-vars.yml) with the required values
+
+  ```bash
+  # L1 chain ID
+  l1_chain_id: ""
+
+  # L1 RPC endpoint
+  l1_rpc: ""
+
+  # L1 RPC endpoint host or IP address
+  l1_host: ""
+
+  # L1 RPC endpoint port number
+  l1_port: ""
+
+  # L1 Beacon endpoint
+  l1_beacon: ""
+
+  # Address of the funded account on L1
+  # Used for optimism contracts deployment
+  l1_address: ""
+
+  # Private key of the funded account on L1
+  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 [setup-vars.yml](./setup-vars.yml) file.
+
+  ```bash
+  LANG=en_US.utf8 ansible-playbook -i localhost, --connection=local run-optimism.yml --extra-vars='{ "target_host": "localhost"}' -kK --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
+    ```
+
+- To run using existing contracts deployment
+
+  - Update `artifact_path` in [`setup-vars.yml`](./setup-vars.yml) file with path to data directory of the existing deployment
+
+  - Run the ansible playbook with `"existing_contracts_deployment": 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", "existing_contracts_deployment":  true}' -kK --user $USER
+    ```
+
+## Check Deployment Status
+
+- Run the following command in the directory where the optimism-deployment is created
+
+  - Follow optimism contracts deployment logs:
+
+    ```bash
+    laconic-so deployment --dir optimism-deployment logs -f fixturenet-optimism-contracts
+    ```
+
+  - Check L2 logs:
+
+    ```bash
+    laconic-so deployment --dir optimism-deployment logs -f op-geth
+
+    # Ensure new blocks are getting created
+    ```
