+## Create Validator
+
+- Get your private key from testnet deployment:
+
+  ```bash
+  # Replace <testnet-deployment-dir> with the absolute path to the testnet deployment directory and <key-name> with the name of your key
+  docker run -it \
+  -v <testnet-deployment-dir>/data/laconicd-data:/root/.laconicd \
+  cerc/laconicd:local bash -c "laconicd keys export <key-name> --unarmored-hex --unsafe"
+  ```
+
+- Export required env vars:
+
+  ```bash
+  # private key of the existing account
+  export PVT_KEY=<private-key-in-hex-format>
+
+  # desired key name
+  export KEY_NAME=<key-name>
+
+  export DATA_DIRECTORY=<data-directory>
+  export MAINNET_DEPLOYMENT_DIR=<mainnet-deployment-dir>
+  ```
+
+- Run ansible playbook to create validator on running chain:
+
+  ```bash
+  ansible-playbook -i localhost, -c local playbooks/validator/create-validator.yml
+  ```
+
+- Check the validator list:
+
+  ```bash
+  laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR exec laconicd 'laconicd query staking validators'
