-# Powershell completion for docker
-
-### Prerequisite
-# Docker.exe needs to be in your PATH.
-# If the command is not found, you will need to add a docker alias or add the docker installation folder (e.g. `%ProgramFiles%\Docker Toolbox`) to your PATH environment variable.
-
-### Installation (Latest stable)
-# Windows 10 / Windows Server 2016: 
-# 1. Open a powershell prompt
-# 2. Run `Install-Module -Scope CurrentUser posh-docker`
-#
-# Earlier Windows versions:
-# 1. Install [PackageManagement PowerShell Modules Preview](https://www.microsoft.com/en-us/download/details.aspx?id=49186)
-# 2. Open a powershell prompt
-# 3. Run `Install-Module -Scope CurrentUser posh-docker`
-
-### Installation (From source)
-# Copy this file to the %userprofile%\Documents\WindowsPowerShell\Modules\posh-docker directory (create directories as needed)
-
-### Usage
-# After installation, execute the following line to enable autocompletion for the current powershell session:
-#
-# Import-Module posh-docker
-#
-# To make it persistent, add the above line to your profile. For example, run `notepad $PROFILE` and insert the line above.
