+Use the Terraform plugin to apply the infrastructure configuration contained within the repository. The following parameters are used to configure this plugin:
+
+* `dryRun` - if true, calculates a plan but does __NOT__ apply it.
+* `remote` - contains the configuration for the Terraform remote state tracking.
+  * `backend` - the Terrafrom remote state backend to use.
+  * `config` - a map of configuration parameters for the remote state backend. Each value is passed as a `-backend-config=<key>=<value>` option.
+* `vars` - a map of variables to pass to the Terraform `plan` and `apply` commands. Each value is passed as a `-var <key>=<value>` option.
+
+The following is a sample Terraform configuration in your .drone.yml file:
+
+```yaml
+deploy:
+  terraform:
+    image: objectpartners/drone-terraform:latest
