+
+`winpkg` is a Go (Golang) module to pull the latest version of a Chocolatey package.
+Chocolatey here is a Windows package manager.
+
+
+## Requirements
+
+This Go module is intended to support the ~~two~~ most recent ~~minor releases~~ release of Go.
+Currently this is Go v1.18.x and v1.19.x.
+
+
+## Installation
+
+`winpkg` is a Go module intended to be used as a library.
+So the best way to "install" it is to import into your own code and then run `go mod tidy` to get the source code downloaded.
+
+```go
+import(
+	"github.com/gopherlibs/winpkg/winpkg"
+)
+```
+
+
+## Usage
+
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"github.com/gopherlibs/winpkg/winpkg"
+)
+
+func main() {
+
+	// Let's get the latest version of the 'git' package
+	if ver, err := winpkg.GetVersion( "git" ); err != nil {
+		fmt.Println(err)
+	} else {
+		fmt.Println(ver)
+	}
+}
+```
+
+
+## Development
+
+This module is written and tested with Go v1.18+ in mind.
+`go fmt` is your friend.
+Please feel free to open Issues and PRs are you see fit.
+Any PR that requires a good amount of work or is a significant change, it would be best to open an Issue to discuss the change first.
+
+
