+
+Inputs - Required:
+
+ - `template_name` - Relative path and file name to the template file to render
+ - `template_vars` - Map of variables which will be substituted into the template
+ - `rendered_file_name` - Name of the rendered template file which will be copied onto the vm
+ - `host` -  IP address or DNS resolveable hostname to the bastion/taget vm
+ - `ssh_private_key` - SSH Private Key File
+
+
+Inputs - Optional: 
+
+ - `bastion_user_name` - default = "ubuntu", Name of the user on the bastion/target vm to be used for ssh
+ - `rendered_file_destination` - default = "/home/ubuntu", Absolute folder of where to copy the rendered file to
+
+Outputs:
+
+ - `rendered_file_contents` - Outputs the contents of the rendered file
+ - `rendered_file_location` - Path to the folder and rendered file name
+
+
+Example Usage:
+
+```hcl
+module "stuff" {
+    source                   = "github.com/cweibel/terraform-module-remote-exec-template.git?ref=0.0.1"
+
+    template_name            = "templates/configure-mgmt-bosh-rds.tpl"
+    template_vars            = {
+                                  pickles = "mypickles"
+                               }
+    rendered_file_name       = "hijason.sh"
+    host                     = module.bastion.box-bastion-public
+    ssh_private_key          = file(var.aws_key_file)
+
+}
