+### 🔑 SSH Key Format
+
+When loading SSH keys, you can specify the format using the `ssh-format` query parameter. This is useful when you need the private key in a specific format like OpenSSH.
+
+```yml
+- name: Load SSH key
+  uses: 1password/load-secrets-action@v3
+  env:
+    OP_SERVICE_ACCOUNT_TOKEN: ${{ secrets.OP_SERVICE_ACCOUNT_TOKEN }}
+    # Load SSH private key in OpenSSH format
+    SSH_PRIVATE_KEY: op://vault/item/private key?ssh-format=openssh
+```
+
+For more details on secret reference syntax, see the [1Password CLI documentation](https://developer.1password.com/docs/cli/secret-reference-syntax/#ssh-format-parameter).
