+## L2 Optimism
+
+* Stack: <https://git.vdb.to/cerc-io/fixturenet-optimism-stack>
+
+* Source repos:
+  * <github.com/ethereum-optimism/optimism@v1.7.7>
+  * <github.com/ethereum-optimism/op-geth@v1.101315.2>
+
+* Target dir: `/srv/l2/optimism-deployment`
+
+* Cleanup an existing deployment if required:
+
+  ```bash
+  cd /srv/l2
+
+  # Stop the deployment
+  laconic-so deployment --dir optimism-deployment stop --delete-volumes
+
+  # Remove the deployment dir
+  sudo rm -rf optimism-deployment
+  ```
+
+### Prerequisites
+
+* Ansible: see [installation](https://git.vdb.to/cerc-io/ops#installation)
+
+### Setup
+
+* Clone the `cerc-io/ops` repository (TODO: replace):
+
+  ```bash
+  git clone git@github.com:deep-stack/ops.git
+
+  cd ops
+  ```
+
+* The following commands have to be executed in `ops/vulcanize/l2-setup` directory (TODO: remove)
+
+  ```bash
+  cd ./vulcanize/l2-setup
+  ```
+
+* Edit `l2-config.env.j2` and fill in the following values:
+
+  ```bash
+  # Chain ID of the L1 chain (Sepolia: 11155111)
+  CERC_L1_CHAIN_ID=11155111
+
+  # L1 RPC endpoint
+  CERC_L1_RPC=
+
+  # L1 RPC endpoint host or IP address
+  CERC_L1_HOST=
+
+  # L1 RPC endpoint port number
+  CERC_L1_PORT=
+
+  # Account credentials for the Admin account
+  # Used for Optimism contracts deployment and funding other generated accounts
+  CERC_L1_ADDRESS=
+  CERC_L1_PRIV_KEY=
+
+  # Funding amount for Optimism Proposer account on L1 (default: 0.2 ether)
+  CERC_L2_PROPOSER_AMOUNT=
+
+  # Funding amount for Optimism Batcher account on L1 (default: 0.1 ether)
+  CERC_L2_BATCHER_AMOUNT=
+  ```
+
+* Update the target dir in `vars.yml`:
+
+  ```bash
+  sed -i 's|^l2_directory:.*|l2_directory: /srv/l2|' vars.yml
+
+  # Will create deployment at /srv/l2/optimism-deployment
+  ```
+
+### Run
+
+* Setup and run L2 by executing the `run-optimism.yml` Ansible playbook:
+
+  ```bash
+  LANG=en_IN.utf8 ansible-playbook -i localhost, --connection=local run-optimism.yml --extra-vars='{ "target_host": "localhost"}' --user $USER
+  ```
+
+  * For skipping container build, run with `"skip_container_build" : true`:
+
+    ```bash
+    LANG=en_IN.utf8 ansible-playbook -i localhost, --connection=local run-optimism.yml --extra-vars='{"target_host" : "localhost", "skip_container_build": true}' -kK --user $USER
+    ```
