-## Why doesn't this work with `http.Handler`?
+## Why can't I retrieve parameters with `http.Handler`?
-**It does!** The router itself implements the `http.Handler` interface. Moreover the router provides convenient [adapters for `http.Handler`][Router.Handler]s and [`http.HandlerFunc`][Router.HandlerFunc]s which allows them to be used as a [`httprouter.Handle`][Router.Handle] when registering a route. The only disadvantage is, that no parameter values can be retrieved when a `http.Handler` or `http.HandlerFunc` is used, since there is no efficient way to pass the values with the existing function parameters. Therefore [`httprouter.Handle`][Router.Handle] has a third function parameter.

-Just try it out for yourself, the usage of HttpRouter is very straightforward. The package is compact and minimalistic, but also probably one of the easiest routers to set up.

+If you want to access parameters, your have to use the [`httprouter.Handle`][Router.Handle] type for those handles.
## Where can I find Middleware *X*?
This package just provides a very efficient request router with a few extra features. The router is just a [`http.Handler`][http.Handler], you can chain any http.Handler compatible middleware before the router, for example the [Gorilla handlers](http://www.gorillatoolkit.org/pkg/handlers). Or you could [just write your own](https://justinas.org/writing-http-middleware-in-go/), it's very easy!
+Pre- / and postprocessing of requests can be applied by using a custom [`router.Wrap`][Router.Wrap] function.

Alternatively, you could try [a web framework based on HttpRouter](#web-frameworks-based-on-httprouter).
