+
+# Using PowerShell DSC
+
+Windows PowerShell Desired State Configuration (DSC) is a configuration
+management tool that extends the existing functionality of Windows PowerShell.
+DSC uses a declarative syntax to define the state in which a target should be
+configured. More information about PowerShell DSC can be found at
+http://technet.microsoft.com/en-us/library/dn249912.aspx.
+
+## Requirements
+
+To use this guide you'll need a Windows host with PowerShell v4.0 or newer.
+
+The included DSC configuration script also uses the official PPA so
+only an Ubuntu target is supported. The Ubuntu target must already have the
+required OMI Server and PowerShell DSC for Linux providers installed. More
+information can be found at https://github.com/MSFTOSSMgmt/WPSDSCLinux. The
+source repository listed below also includes PowerShell DSC for Linux
+installation and init scripts along with more detailed installation information.
+
+## Installation
+
+The DSC configuration example source is available in the following repository:
+https://github.com/anweiss/DockerClientDSC. It can be cloned with:
+
+    $ git clone https://github.com/anweiss/DockerClientDSC.git
+
+## Usage
+
+The DSC configuration utilizes a set of shell scripts to determine whether or
+not the specified Docker components are configured on the target node(s). The
+source repository also includes a script (`RunDockerClientConfig.ps1`) that can
+be used to establish the required CIM session(s) and execute the
+`Set-DscConfiguration` cmdlet.
+
+More detailed usage information can be found at
+https://github.com/anweiss/DockerClientDSC.
+
+### Run Configuration
+The Docker installation configuration is equivalent to running:
+
+```
+apt-get install docker.io
+ln -sf /usr/bin/docker.io /usr/local/bin/docker
+sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker.io
+```
+
+Ensure that your current working directory is set to the `DockerClientDSC`
+source and load the DockerClient configuration into the current PowerShell
+session
+
+```powershell
+. .\DockerClient.ps1
+```
+
+Generate the required DSC configuration .mof file for the targeted node
+
+```powershell
+DockerClient -Hostname "myhost"
+```
+
+A sample DSC configuration data file has also been included and can be modified
+and used in conjunction with or in place of the `Hostname` parameter:
+
+```powershell
+DockerClient -ConfigurationData .\DockerConfigData.psd1
+```
+
+Start the configuration application process on the targeted node
+
+```powershell
+.\RunDockerClientConfig.ps1 -Hostname "myhost"
+```
+
+The `RunDockerClientConfig.ps1` script can also parse a DSC configuration data
+file and execute configurations against multiple nodes as such:
+
+```powershell
+.\RunDockerClientConfig.ps1 -ConfigurationData .\DockerConfigData.psd1
+```
+
+### Images
+Image configuration is equivalent to running: `docker pull [image]`.
+
+Using the same Run Configuration steps defined above, execute `DockerClient`
+with the `Image` parameter:
+
+```powershell
+DockerClient -Hostname "myhost" -Image node
+```
+
+The configuration process can be initiated as before:
+
+```powershell
+.\RunDockerClientConfig.ps1 -Hostname "myhost"
+```
+
+### Containers
+Container configuration is equivalent to running:
+`docker run -d --name="[containername]" [image] '[command]'`.
+
+Using the same Run Configuration steps defined above, execute `DockerClient`
+with the `Image`, `ContainerName`, and `Command` parameters:
+
+```powershell
+DockerClient -Hostname "myhost" -Image node -ContainerName "helloworld" `
+-Command 'echo "Hello World!"'
+```
+
+The configuration process can be initiated as before:
+
+```powershell
+.\RunDockerClientConfig.ps1 -Hostname "myhost"
+```
