 ### Listing Routes
 
 Routes on a mux can be listed using the Router.Walk method—useful for generating documentation:
 
 ```go
 package main
 
 import (
     "fmt"
     "net/http"
 
     "github.com/gorilla/mux"
 )
 
 func handler(w http.ResponseWriter, r *http.Request) {
     return
 }
 
 func main() {
     r := mux.NewRouter()
     r.HandleFunc("/", handler)
     r.HandleFunc("/products", handler)
     r.HandleFunc("/articles", handler)
     r.HandleFunc("/articles/{id}", handler)
     r.Walk(func(route *mux.Route, router *mux.Router, ancestors []*mux.Route) error {
         t, err := route.GetPathTemplate()
         if err != nil {
             return err
         }
         fmt.Println(t)
         return nil
     })
     http.Handle("/", r)
 }
 ```
