 ## Graceful Shutdown Recipe
 
-### Using [grace](https://github.com/facebookgo/grace)
+Echo now ships with graceful server termination inside it, to accomplish it Echo uses  `github.com/tylerb/graceful` library.
+
+By Default echo uses 15 seconds as shutdown timeout, giving 15 secs to open connections at the time the server starts to shut-down.
+
+In order to change this default 15 seconds you could change the `ShutdownTimeout` property of your Echo instance as needed by doing something like:
 
 `server.go`
