-## Config
+Use the SSH plugin to execute commands on a remote server. The below pipeline configuration demonstrates simple usage:
-
-The following parameters are used to configure the plugin:
-
-* **host** - address or IP of the remote machine
-* **port** - port to connect to on the remote machine
-* **user** - user to log in as on the remote machine
-* **passsword** - password to log in as on the remote machine
-* **key** - private SSH key for the remote machine
-* **sleep** - sleep for seconds between host connections
-* **timeout** - timeout for the tcp connection attempt
-* **script** - list of commands to execute
-
-The following secret values can be set to configure the plugin.
-
-* **SSH_HOST** - corresponds to **host**
-* **SSH_PORT** - corresponds to **port**
-* **SSH_USER** - corresponds to **user**
-* **SSH_PASSWORD** - corresponds to **password**
-* **SSH_KEY** - corresponds to **key**
-* **SSH_SLEEP** - corresponds to **sleep**
-* **SSH_TIMEOUT** - corresponds to **timeout**
