 [Ring](https://github.com/ring-clojure/ring) is a Clojure web applications library inspired by Python's WSGI and Ruby's Rack. By abstracting the details of HTTP into a simple, unified API, Ring allows web applications to be constructed of modular components that can be shared among a variety of applications, web servers, and web frameworks.

-Ring-router adds support for [handlers](https://github.com/ring-clojure/ring/wiki/Concepts#handlers), [middleware](https://github.com/ring-clojure/ring/wiki/Concepts#middleware) and routing based on `:request-method`. Ring-router is created with `reitit.ring/router` function. It uses a custom route compiler, creating a optimized data structure for handling route matches, with compiled middleware chain & handlers for all request methods. It also ensures that all routes have a `:handler` defined. `reitit.ring/ring-handler` is used to create a Ring handler out of ring-router.

 # Request-method based routing
 
-Handler are also looked under request-method keys: `:get`, `:head`, `:patch`, `:delete`, `:options`, `:post` or `:put`. Top-level handler is used if request-method based handler is not found.
+Handlers can be placed either to the top-level (all methods) or under a specific method (`:get`, `:head`, `:patch`, `:delete`, `:options`, `:post`, `:put` or `:trace`). Top-level handler is used if request-method based handler is not found.

+By default, the `:options` route is generated for all paths - to enable thing like [CORS](https://en.wikipedia.org/wiki/Cross-origin_resource_sharing).
