+# How To Windows
+
+This is the PowerShell script to run all go tests for Kustomize on a windows based platform which mimics /build/pre-commit.sh
+
+## Pre-Reqs:
+  - (obviously) PowerShell installed
+    - PowerShell Core is supported
+  - go installed
+  - golangci-lint installed
+  - mdrip installed
+
+This script should output to the current console and return an exit code if all tests are successful(0) or any failed(1).
+
+### If you are tryin to run these tests locally you can follow these instructions.
+
+Assume: 
+  - Running a stock Windows 10 system
+  - Local Admin rights.
+  - You can open [PowerShell as administrator](http://lmgtfy.com/?iie=1&q=How+to+open+powershell+as+administrator)
+  - You should be knowledgeable enough to pull source for packages into your GO ```src``` directory
+    -  Yes, this means you also need to know a bit about **git** usually
+
+
+#### Step 1 - Install Go
+  - [Install Go](https://golang.org/dl/) - please use the msi
+    - If you use chocolatey - it's using the zip not msi and assumptions on where go is located are made for you.
+#### Step 2 - Install Go Packages
+  - Open new PowerShell Administrative window
+    - Install golangci-lint
+      - ```go get -u github.com/golangci/golangci-lint/cmd/golangci-lint```
+    - Install mdrip
+      - ```go get github.com/monopole/mdrip```
+
+You should now be able to issue these commands and see comparable responses
+
+```
+C:\...> golangci-lint --help
+Smart, fast linters runner. Run it in cloud for every GitHub pull request on https://golangci.com
+...
+
+C:\...> mdrip --help
+Usage:  C:\_go\bin\mdrip.exe {fileName}...
+...
+```
+
+#### Step 3 - Get Source and Test
+- In your GoRoot src
+  - ```Example: C:\_go\src```
+- Navigate to the Kustomize bin directory
+  - ```Example: C:\_go\src\sigs.k8s.io\kustomize\bin```
+- Now Execute:
+  - ```.\Invoke-PreCommit.ps1```
+
+This should run all pre-commit tests thus defined in the script.
