-# GoDoc
-
-See <https://pkg.go.dev/git.rootprojects.org/root/go-gitver/v2>.
-
-# How it works
-
-1. You define the fallback version and version printing in `main.go`:
-
-```go
-//go:generate go run git.rootprojects.org/root/go-gitver/v2
-
-package main
-
-import (
-	"fmt"
-	"strings"
-)
-
-var (
-	commit  = "0000000"
-	version = "0.0.0-pre0+0000000"
-	date    = "0000-00-00T00:00:00+0000"
-)
-
-func main() {
-	if (len(os.Args) > 1 && "version" == strings.TrimLeft(os.Args[1], "-")) {
-		fmt.Printf("Foobar v%s (%s) %s\n", version, commit[:7], date)
-	}
-	// ...
-}
-```
-
-2. You `go generate` or `go run git.rootprojects.org/root/go-gitver/v2` to generate `xversion.go`:
-
-```go
-package main
-
-func init() {
-    commit  = "0921ed1e"
-    version = "1.1.2"
-    date    = "2019-07-01T02:32:58-06:00"
-}
-```
 
 # Demo
 
-Generate an `xversion.go` file:
-
 ```bash
-go run git.rootprojects.org/root/go-gitver/v2
+go run git.rootprojects.org/root/go-gitver
-cat xversion.go
-```
-
-```go
-// Code generated by go generate; DO NOT EDIT.
-package main
-
-func init() {
-	commit  = "6dace8255b52e123297a44629bc32c015add310a"
-	version = "1.1.4-pre2+g6dace82"
-	date    = "2020-07-16T20:48:15-06:00"
-}
-```
-
-<small>**Note**: The file is named `xversion.go` by default so that the
-generated file's `init()` will come later, and thus take priority, over
-most other files.</small>
-
-See `go-gitver`s self-generated version:
-
-```bash
-go run git.rootprojects.org/root/go-gitver/v2 version
-```
