-This code will generate an assets_vfsdata.go file with `var assets http.FileSystem = ...` that statically implements the contents of "assets" directory.
+Package `vfsgen` is a Go code generator library. It has a `Generate` function that takes an input filesystem (as a [`http.FileSystem`](https://godoc.org/net/http#FileSystem) type), and generates a Go code file that statically implements the contents of the input filesystem.
+
+For example, we can use [`http.Dir`](https://godoc.org/net/http#Dir) as a `http.FileSystem` implementation that uses the contents of the `/path/to/assets` directory:
 
 ```Go
-var fs http.FileSystem = http.Dir("assets")
+var fs http.FileSystem = http.Dir("/path/to/assets")
+```
 
+Now, when you execute the following code:
+
+```Go
 err := vfsgen.Generate(fs, vfsgen.Options{})
 if err != nil {
 	log.Fatalln(err)
 }
 ```
 
+An assets_vfsdata.go file will be generated in the current directory:
+
+```Go
+// Code generated by vfsgen; DO NOT EDIT.
+
+package main
+
+import ...
+
+// assets statically implements the virtual filesystem provided to vfsgen.Generate.
+var assets http.FileSystem = ...
+```
+
 Then, in your program, you can use `assets` as any other [`http.FileSystem`](https://godoc.org/net/http#FileSystem), for example:
 
 ```Go
 file, err := assets.Open("/some/file.txt")
-if err != nil { ... }
+if err != nil {
+	return err
+}
 defer file.Close()
 ```

+`vfsgen` can be more useful when combined with build tags and go generate directives. This is described below.

 ### `go generate` Usage
 
 vfsgen is great to use with go generate directives. The code invoking `vfsgen.Generate` can go in an assets_generate.go file, which can then be invoked via "//go:generate go run assets_generate.go". The input virtual filesystem can read directly from disk, or it can be more involved.
