+* Stack: <https://git.vdb.to/cerc-io/nitro-stack>
+
+* Source repos: <https://github.com/cerc-io/go-nitro>
+
+* Target dir: `/srv/bridge/bridge-deployment`
+
+* Cleanup an existing deployment if required:
+
+  ```bash
+  cd /srv/bridge
+
+  # Stop the deployment
+  laconic-so deployment --dir bridge-deployment stop --delete-volumes
+
+  # Remove the deployment dir
+  sudo rm -rf bridge-deployment
+  ```
+
+### Setup
+
+* Clone the `cerc-io/testnet-ops` repository:
+
+  ```bash
+  cd /srv
+
+  # Can be skipped if repo already exists
+  git clone git@git.vdb.to:cerc-io/testnet-ops.git
+
+  cd testnet-ops/nitro-bridge-setup
+  ```
+
+* Create the required vars file:
+
+  ```bash
+  cp bridge-vars-example.yml bridge-vars.yml
+  ```
+
+* Edit `bridge-vars.yml` and fill in the following values:
+
+  ```bash
+  # L1 WS endpoint
+  l1_nitro_chain_url: ""
+
+  # L2 WS endpoint
+  l2_nitro_chain_url: ''
+

+
+* Update the target dir in `setup-vars.yml`:
+
+  ```bash
+  sed -i 's|^nitro_directory:.*|nitro_directory: /srv/bridge|' vars.yml
+
+  # Will create deployment at /srv/bridge/bridge-deployment
+  ```
+
+### Run
+
+* Setup and run L2 by executing the `run-nitro-bridge.yml` Ansible playbook:
+
+  ```bash
+  LANG=en_US.utf8 ansible-playbook -i localhost, --connection=local run-nitro-bridge.yml --extra-vars='{ "target_host": "localhost"}' --user $USER
+  ```
+
+  * For skipping container build, run with `"skip_container_build" : true`:
+
+    ```bash
+    LANG=en_US.utf8 ansible-playbook -i localhost, --connection=local run-nitro-bridge.yml --extra-vars='{"target_host" : "localhost", "skip_container_build": true}' -kK --user $USER
