+# Access Go Docs Offline
+
+The Go language has a wonderfully comprehensive standard library. There is
+documentation for all of it. You can access that documentation anytime if
+you have an internet connection via
+[https://golang.org/doc/](golang.org/doc/).
+
+If you are without an internet connection, you're still in luck. Go has a
+built-in feature for serving the documentation locally _offline_. Just run
+the following command:
+
+```
+$ godoc -http=:6060
+```
+
+and then visit `localhost:6060`.
