+# Run nitro-nodes 
+
+## Setup
+
+- Follow the [installation guide](https://github.com/deep-stack/ops/blob/ag-run-l2/README.md#installation) to setup ansible on your machine
+
+- Ensure laconic-so is installed 
+
+  ```bash
+  laconic-so version
+  ```
+  
+- Clone the ops repo
+
+  ```bash
+  git clone git@github.com:deep-stack/ops.git
+  cd ops
+  git checkout ag-run-l2
+  ```
+
+
+## Run l1, l2 nitro nodes
+
+- Navigate to the `vulcanize/nitro-node-setup` directory
+
+  ```bash  
+  cd vulcanize/nitro-node-setup
+  ```
+
+- Copy the `nitro-vars-example.yml` vars file
+
+  ```bash
+  cp nitro-vars-example.yml nitro-vars.yml
+  ```
+
+<!-- TODO: Provide nitro environment variables to user -->
+- Edit [`nitro-vars.yml`](./nitro-vars.yml) and fill in the following values
+
+  ```bash
+  # URL endpoint of the L1 chain
+  l1_nitro_chain_url: ""
+
+  # URL endpoint of the L2 chain
+  l2_nitro_chain_url: ""
+
+  # Private key for your nitro address
+  nitro_sc_pk: ""
+
+  # Private key of the account on chain that is used for funding channels in Nitro node
+  nitro_chain_pk: ""
+
+  # Contract address of NitroAdjudicator
+  na_address: ""
+
+  # Contract address of VirtualPaymentApp
+  vpa_address: ""
+
+  # Contract address of ConsensusApp
+  ca_address: ""
+
+  # Contract address of bridge
+  bridge_address: ""
+
+  # IP address of the bridge node
+  nitro_bridge_ip: ""
+
+  # Publically accessible IP address of your nitro node
+  nitro_node_ip: ""
+  ```
+
+- To run nitro nodes, execute the `run-nitro-node.yml` Ansible playbook by running the following command.
+
+  NOTE: By default, deployments are created in the `nitro-node-setup/out` directory. If you need to change this location, you can update the `nitro_directory` variable in the [setup-vars.yml](./setup-vars.yml) file.
+
+  ```bash
+  LANG=en_IN.utf8 ansible-playbook -i localhost, --connection=local run-nitro-node.yml --extra-vars='{ "target_host": "localhost"}' --user $USER
+  ```
+
+  - If you want to skip building the containers, set `"skip_container_build" : true` in the `--extra-vars` parameter:
+
+    ```bash
+    LANG=en_IN.utf8 ansible-playbook -i localhost, --connection=local run-nitro-node.yml --extra-vars='{ "target_host": "localhost", "skip_container_build": true }' --user $USER
+    ```
+
+- Follow steps from [Demo](https://git.vdb.to/cerc-io/nitro-stack/src/branch/main/nitro-bridge-demo.md#demo) to create mirror channels on L2, create virtual channel and make payments
