-# HTTP Middleware
-
-RoadRunner HTTP server uses default Golang middleware model which allows you to extend it using custom or
-community-driven middleware. The simplest service with middleware registration would look like:
-
-```golang
-package middleware
-
-import (
- "net/http"
-)
-
-const PluginName = "middleware"
-
-type Plugin struct{}
-
-// to declare plugin
-func (g *Plugin) Init() error {
-    return nil
-}
-
-func (g *Plugin) Middleware(next http.Handler) http.Handler {
-    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
-    // do something
-    // ...
-    // continue request through the middleware pipeline
-    next.ServeHTTP(w, r)
- })
-}
-
-// Middleware/plugin name.
-func (g *Plugin) Name() string {
-    return PluginName
-}
-```
-
-> Middleware must correspond to the following [interface](https://github.com/spiral/roadrunner/blob/master/plugins/http/plugin.go#L37) and be named.
-
-We have to register this service after in the [`internal/container/plugin.go`](https://github.com/spiral/roadrunner-binary/blob/master/internal/container/plugins.go#L31) file in order to properly resolve dependency:
-
-```golang
-import (
-    "middleware"
-)
-
-func Plugins() []interface{} {
-	return []interface{}{
-    // ...
-    
-    // middleware
-    &middleware.Plugin{},
-    
-    // ...
- }
-```
-
-You should also make sure you configure the middleware to be used via the [config or the command line](https://roadrunner.dev/docs/intro-config) otherwise the plugin will be loaded but the middleware will not be used with incoming requests.
-
-```yaml
-http:
-    # provide the name of the plugin as provided by the plugin in the example's case, "middleware"
-    middleware: [ "middleware" ]
-```
-
-### PSR7 Attributes
-
-You can safely pass values to `ServerRequestInterface->getAttributes()` using [attributes](https://github.com/spiral/roadrunner/blob/master/plugins/http/attributes/attributes.go) package:
-
-```golang
-func (s *Service) middleware(next http.HandlerFunc) http.HandlerFunc {
- return func(w http.ResponseWriter, r *http.Request) {
-     r = attributes.Init(r)
-     attributes.Set(r, "key", "value")
-            next(w, r)
- }
-}
-```
