+## About this plugin
+
+The Terraform plugin for [Jenkins](https://jenkins.io) adds an installer for [Terraform](https://hashicorp.com/terraform) and provides a job build wrapper for creating (and destroying) infrastructure. 
+
+The installer generates a list of Terraform binaries for installation from [bintray.com](http://bintray.com), see [Terraform Crawler](https://github.com/jenkinsci/backend-crawler/blob/master/terraform.groovy).
 
 ## Usage
 
-This plugin adds an installer for Terraform and provides a build wrapper for creating and destroying infrastructure.
+### Tool Installation
 
-The installer generates a list of Terraform binaries for installation from [bintray.com](http://bintray.com), see [Terraform Crawler](https://github.com/jenkinsci/backend-crawler/blob/master/terraform.groovy).
+Terraform binaries can be installed via  _Manage Jenkins > Global Tool Configuration_. 
+Select a label, version and platform to install.

+
+### Job Configuration
+
+This plugin works as a build wrapper and can be invoked by selecting
+Terraform under the Build Environment section of your job configuration.
+
+A workspace directory **terraform-plugin** will be created, this is
+where temporary files are created and automatically deleted after runs.
+
+This directory also contains the generated tfstate file
+**terraform-plugin.tfstate**.
+
+This generated tfstate file is not deleted and is always passed to
+Terraform using
+**-state=workspace/terraform-plugin/terraform-plugin.tfstate** as an
+extra safety measure so as to not use any other tfstate file you might
+have in a workspace.
+
+The first step is to decide how you would like to pass your
+configurations to Terraform, there are 2 options:
+
+#### Option 1: Configuration text
+
+![](https://wiki.jenkins.io/download/thumbnails/85590094/terraform-configuration-text.png?version=1&modificationDate=1449190253000&api=v2)
+
+This option allows you to copy what would be in a resource file (.tf)
+into a textarea. This text will then be written to a temporary file
+(workspace/terraform-plugin/terraform-TEMP.tf) and parsed by Terraform.
+
+#### Option 2: Configuration path
+
+![](https://wiki.jenkins.io/download/thumbnails/85590094/terraform-configuration-path.png?version=1&modificationDate=1449190352000&api=v2)
+
+This option provides a directory path (relative to your workspace) to
+enter where your configuration files (.tf) exist. If no path is given,
+it defaults to the workspace path.
+
+### Additional configuration options
+
+#### Update modules
 
-See the Jenkins plugin wiki for more details: [Terraform Plugin Wiki](https://wiki.jenkins-ci.org/display/JENKINS/Terraform+Plugin).

-# Developer Instructions
+Terraform will run the get command by default, use this option to run
+Terraform get with the -update flag.
+
+#### Resource variables 
+
+![](https://wiki.jenkins.io/download/thumbnails/85590094/terraform-resource-variables.png?version=1&modificationDate=1449190478000&api=v2)
+
+If you are using resource files that reference external variables, set
+these variables here.
+
+These variables will be written to a temporary file
+(workspace/terraform-plugin/variables-TEMP.tfvars) and will be passed to
+Terraform using the **--var-file=** option.
+
+
+### Advanced
+
+![](https://wiki.jenkins.io/download/thumbnails/85590094/terraform-destroy.png?version=1&modificationDate=1449190568000&api=v2)
+
+If you want to destroy the architecture you have created once the build
+is complete, click the advanced button and check Destroy On Build
+Completion.
+
+This will call Terraform with the **destroy --force** option which will
+look at the generated terraform-plugin.tfstate file
+(workspace/terraform-plugin/terraform-plugin.tfstate) and destroy
+everything under Terraform supervision.
