+## Setup Remote Hosts
+
+To run the playbooks on a remote machine, follow these steps:
+
+- In the [`nitro-bridge-setup`](./) directory, create a new file named hosts.ini:
+
+   ```bash
+   cp ../example-hosts.ini hosts.ini
+   ```
+
+- Edit the [`hosts.ini`](./hosts.ini) file to run the playbook on a remote machine
+
+   ```bash
+  [nitro_host]
+  hostname ansible_host= ansible_user= ansible_ssh_common_args='-o ForwardAgent=yes'
+   ```
+
+  - Replace `host_name` with the alias of your choice.
+  - Replace `<TARGET_IP>` with the IP address or hostname of the target machine.
+  - Replace `<SSH_USER>` with the SSH username (e.g., dev, ubuntu).
+
+- Verify that you are able to connect to the host using the following command
+
+  ```bash
+  ansible all -m ping -i hosts.ini
+  ```
