+# Windows native docker image
+
+## Why?
+
+A linux docker image is available for GitVersion [here](https://hub.docker.com/r/ilucker/gitversion/)
+
+This is the preferred docker image to use. However, it's also convenient to have a native windows
+docker image available, at least until either:
+
+* dotnet core build of GitVersion is available
+* linux and native windows containers can be run side-by-side (see [--platform flag](https://blog.docker.com/2018/02/docker-for-windows-18-02-with-windows-10-fall-creators-update/#h.kiztgok2bqti))
+
+## Use docker image
+
+``` powershell
+docker run --rm -v "$(pwd):C:\repo" gittools/gitversion-win
+```
+
+The above command is the equivalent to running (assuming you have GitVersion.exe in your `$PATH`):
+
+``` cmd
+GitVersion
+```
+
+## Build docker image
+
+1. Open powershell prompt
+2. Change directory to the `docker-for-windows` directory
+    * eg: `cd C:\Git\GitVersion\docker-for-windows`
+3. Run build.ps1 with the appropriate arguments
+    * eg: `.\build.ps1 -Version 4.0.0-beta.13 -VersionZip 4.0.0-beta0013`
+
+## Publish image
+
+1. Open powershell prompt
+2. Login to docker registry you will be pushing to (see [docker login](https://docs.docker.com/engine/reference/commandline/login/) command)
+3. Change directory to the `docker-for-windows` directory
+    * eg: `cd C:\Git\GitVersion\docker-for-windows`
+3. Run build.ps1 with the appropriate arguments
+    * eg: `.\build.ps1 -Version 4.0.0-beta.13 -VersionZip 4.0.0-beta0013` -Publish
