+| Name          | Required | Type   | Description                     |
+|---------------|----------|--------|---------------------------------|
+| `host`        | Yes      | String | Remote hostname.                |

 You may encode your private key in base64 via:
 
-    openssl base64 -in {PRIVATE_KEY_FILE} -out {OUTPUT_PRIVATE_KEY_FILE}
+```shell
+openssl base64 -in {PRIVATE_KEY_FILE} -out {OUTPUT_PRIVATE_KEY_FILE}
+```
 
 Store that in GitHub Secrets to securely pass to the action.

+- name: SSH Socket Setup
+  id: ssh-socket-action
+  uses: sourcetoad/ssh-socket-action@v1.0.0
+  with:
+      host: github.com
+      port: 22 # optional

 ## Development
 Make `ncc` available in your build environment:
-
-    npm i -g @zeit/ncc
+```shell
+npm i -g @zeit/ncc
+```
 
 Install package dependencies:
-
-    yarn install
+```shell
+yarn install
+```
 
 Build `dist/index.js`:
-
-    ncc build index.js
-
+```shell
+ncc build index.js
+```
