 ```
+
+#### Fatal handlers
+
+Logrus can register one or more functions that will be called when any `fatal`
+level message is logged. The registered handlers will be executed before
+logrus performs a `os.Exit(1)`. This behavior may be helpful if callers need
+to gracefully shutdown. Unlike a `panic("Something went wrong...")` call which can be intercepted with a deferred `recover` a call to `os.Exit(1)` can not be intercepted.
+
+```
+...
+handler := func() {
+  // gracefully shutdown something...
+}
+logrus.RegisterExitHandler(handler)
+...
+```
+
+#### Thread safety
+
+By default Logger is protected by mutex for concurrent writes, this mutex is invoked when calling hooks and writing logs.
+If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking.
+
+Situation when locking is not needed includes:
+
+* You have no hooks registered, or hooks calling is already thread-safe.
+
+* Writing to logger.Out is already thread-safe, for example:
+
+  1) logger.Out is protected by locks.
+
+  2) logger.Out is a os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allow multi-thread/multi-process writing)
+
+     (Refer to http://www.notthewizard.com/2014/06/17/are-files-appends-really-atomic/)

-Package context stores values shared during a request lifetime.
-
-For example, a router can set variables extracted from the URL and later
-application handlers can access those values, or it can be used to store
-sessions values to be saved at the end of a request. There are several
-others common uses.
-
-The idea was posted by Brad Fitzpatrick to the go-nuts mailing list:
-
-	http://groups.google.com/group/golang-nuts/msg/e2d679d303aa5d53
-
-Here's the basic usage: first define the keys that you will need. The key
-type is interface{} so a key can be of any type that supports equality.
-Here we define a key using a custom int type to avoid name collisions:
-
-	package foo
-
-	import (
-		"github.com/gorilla/context"
-	)
-
-	type key int
-
-	const MyKey key = 0
-
-Then set a variable. Variables are bound to an http.Request object, so you
-need a request instance to set a value:
-
-	context.Set(r, MyKey, "bar")
-
-The application can later access the variable using the same key you provided:
-
-	func MyHandler(w http.ResponseWriter, r *http.Request) {
-		// val is "bar".
-		val := context.Get(r, foo.MyKey)
-
-		// returns ("bar", true)
-		val, ok := context.GetOk(r, foo.MyKey)
-		// ...
-	}
-
-And that's all about the basic usage. We discuss some other ideas below.
-
-Any type can be stored in the context. To enforce a given type, make the key
-private and wrap Get() and Set() to accept and return values of a specific
-type:
-
-	type key int
-
-	const mykey key = 0
-
-	// GetMyKey returns a value for this package from the request values.
-	func GetMyKey(r *http.Request) SomeType {
-		if rv := context.Get(r, mykey); rv != nil {
-			return rv.(SomeType)
-		}
-		return nil
-	}
-
-	// SetMyKey sets a value for this package in the request values.
-	func SetMyKey(r *http.Request, val SomeType) {
-		context.Set(r, mykey, val)
-	}
-
-Variables must be cleared at the end of a request, to remove all values
-that were stored. This can be done in an http.Handler, after a request was
-served. Just call Clear() passing the request:
-
-	context.Clear(r)
-
-...or use ClearHandler(), which conveniently wraps an http.Handler to clear
-variables at the end of a request lifetime.
-
-The Routers from the packages gorilla/mux and gorilla/pat call Clear()
-so if you are using either of them you don't need to clear the context manually.

-Package `gorilla/mux` implements a request router and dispatcher.
+Package `gorilla/mux` implements a request router and dispatcher for matching incoming requests to
+their respective handler.
 
 The name mux stands for "HTTP request multiplexer". Like the standard `http.ServeMux`, `mux.Router` matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are:
 
+* It implements the `http.Handler` interface so it is compatible with the standard `http.ServeMux`.
 * Requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers.
 * URL hosts and paths can have variables with an optional regular expression.
 * Registered URLs can be built, or "reversed", which helps maintaining references to resources.
 * Routes can be used as subrouters: nested routes are only tested if the parent route matches. This is useful to define groups of routes that share common conditions like a host, a path prefix or other repeated attributes. As a bonus, this optimizes request matching.
-* It implements the `http.Handler` interface so it is compatible with the standard `http.ServeMux`.

 The names are used to create a map of route variables which can be retrieved calling `mux.Vars()`:

+}
 ```
 
 And this is all you need to know about the basic usage. More advanced options are explained below.

+### 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)
+}
+```
+
+### Static Files
+
+Note that the path provided to `PathPrefix()` represents a "wildcard": calling
+`PathPrefix("/static/").Handler(...)` means that the handler will be passed any
+request that matches "/static/*". This makes it easy to serve static files with mux:
+
+```go
+func main() {
+	var dir string
+
+	flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
+	flag.Parse()
+	r := mux.NewRouter()
+
+	// This will serve files under http://localhost:8000/static/<filename>
+	r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
+
+	srv := &http.Server{
+		Handler:      r,
+		Addr:         "127.0.0.1:8000",
+		// Good practice: enforce timeouts for servers you create!
+		WriteTimeout: 15 * time.Second,
+		ReadTimeout:  15 * time.Second,
+	}
+
+	log.Fatal(srv.ListenAndServe())
+}
+```
+
+### Registered URLs
+
 Now let's see how to build registered URLs.
 
 Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling `Name()` on a route. For example:
