+## Ansible Installation
+
+- Install [Ansible](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html#installing-and-upgrading-ansible-with-pip)
+
+- Add location of the directory containing the ansible binary to your `PATH`
+
+- Set Locale Encoding to `UTF-8`
+
+  Ansible requires the locale encoding to be `UTF-8`. You can either use the `LANG` prefix when running Ansible commands or set the system-wide locale
+
+  - Option 1: Use `LANG` Prefix in Commands
+
+    If you prefer not to change the system-wide locale, you can use the `LANG` prefix when running Ansible commands:
+
+    ```bash
+    LANG=en_US.UTF-8 ansible-playbook your_playbook.yml
+    ```
+
+  - Option 2: Set System-Wide Locale
+
+    - Edit the `/etc/default/locale` file:
+
+      ```bash
+      sudo nano /etc/default/locale
+      ```
+
+    - Set the `LANG` variable to en_US.UTF-8:
+
+      ```
+      LANG="en_US.UTF-8"
+      ```
+
+    - Reboot your system or log out and log back in to apply the changes
+
+    - Reference: <https://udhayakumarc.medium.com/error-ansible-requires-the-locale-encoding-to-be-utf-8-detected-iso8859-1-6da808387f7d>
+
+- Verify ansible installation by running the following command:
+
+  ```bash
+  ansible --version
+  # ansible [core 2.17.2]
+  ```
+
+- Install `sshpass` used for automating SSH password authentication
+
+  ```bash
+  sudo apt-get install sshpass
+  ```

+# validator
+
+This directory contains playbooks for setting up and managing a validator on the Laconic chain. There are two main playbooks:
+
+* `create-validator.yml` - Creates a validator on an already running node
+* (Coming soon) `setup-validator.yml` - Sets up and runs a validator node
+
+## Prerequisites
+
+- [Ansible](../README.md#ansible-installation)
+- [Stack orchestrator](https://git.vdb.to/cerc-io/testnet-ops/src/branch/main/stack-orchestrator-setup)
+- Private key or mnemonic of validator account from previous testnet
+  - Use <https://wallet.laconic.com>
+
+## Configuration
+
+* Set the required environment variables:
+  ```bash
+  export DATA_DIRECTORY=/path/to/deployment/parent/directory
+  export DEPLOYMENT_DIR=validator-laconicd-deployment
+  ```
+
+* Copy the example variables file and edit it:
+  ```bash
+  cp validator-vars.example.yml validator-vars.yml
+  ```
+
+* Edit `validator-vars.yml` to set your validator parameters:
+  ```yaml
+  # Chain configuration
+  cerc_moniker: "YourValidatorName"  # Your validator's name
+  cerc_chain_id: "laconic-mainnet"    # Chain ID
+
+  # TODO: Add persistent peer addresses
+  cerc_peers: ""                     # Comma-separated list of peers
+  ```
+
+## Creating a Validator
+
+To create a validator:
+
+* Make sure your validator node is running and synced
+
+<!-- TODO: Add playbook and steps for setting up and running validator node -->
+* Set key name used for importing validator account
+  ```bash
+  export KEY_NAME=<key-name>
+  ```
+
+* Run the create-validator playbook:
+  ```bash
+  ansible-playbook playbooks/validator/create-validator.yml
+  ```
+
+## Verification
+
+After running the playbook, you can verify your validator was created by:
+
+* Check the validator list:
+  ```bash
+  laconic-so deployment --dir $DATA_DIRECTORY/$DEPLOYMENT_DIR exec laconicd 'laconicd query staking validators'
+  ```
+
+* Check your validator's details:
+  ```bash
+  laconic-so deployment --dir $DATA_DIRECTORY/$DEPLOYMENT_DIR exec laconicd 'laconicd query staking validator $(laconicd keys show validator --bech val -a)'
+  ```
