 Create a handy `gdoc` alias for instant symbol lookups:
 
 ```bash
-$ stdsym > ~/.gostdsym
-$ alias gdoc="cat ~/.gostdsym |fzf | xargs go doc "
+stdsym > ~/.gostdsym
+alias gdoc="cat ~/.gostdsym |fzf | xargs go doc "

+If you want to view the results on [pkg.go.dev](https://pkg.go.dev/), use this alias. This example is for macOS, where the open command opens the link in the default browser:
