-# ningle-fbr
-Plugin for ningle to enable file-based routing
+# ningle-fbr (WIP)
+Plugin for [ningle](https://github.com/fukamachi/ningle) and [jingle](https://github.com/dnaeon/cl-jingle) to enable file-based routing
+
+# Usage
+
+To use ningle-fbr, you must use [package-inferred-system](https://asdf.common-lisp.dev/asdf/The-package_002dinferred_002dsystem-extension.html).
+
+`/example.asd`
+```lisp
+(defsystem "example"
+  :class :package-inferred-system
+  :pathname "src"
+  :depends-on ("example/app")
+```
+
+`/src/app.lisp`
+```lisp
+(uiop:define-package #:example
+  (:nicknames #:example/app)
+  (:use #:cl)
+  (:import-from #:ningle)
+  (:import-from #:ningle-fbr))
+(in-package #:example/app)
+
+(defparameter *app* (make-instance 'ningle:<app>))
+
+(defun update-routes ()
+  (ningle-fbr:enable-file-based-routing
+    *app*
+    :dir "src/routes"
+    :system "example"
+    :system-pathname "src"))
+
+(update-routes)
+```
+
+## Static routing
+
+`/src/routes/index.lisp` → `/`
+```lisp
+(uiop:define-package #:example/routes/index
+  (:use #:cl)
+  (:export #:on-get
+           #:on-post
+           #:on-put
+           #:on-delete))
+(in-package #:example/routes/index)
+
+(defun on-get (params)
+  ...)
+
+(defun on-post (params)
+  ...)
+
+(defun on-put (params)
+  ...)
+
+(defun on-delete (params)
+  ...)
+```
+
+## Dynamic routing
+
+A file or directory name prefixed with '=' indicates a dynamic path. 
+
+In the example below, the name parameter can be obtained from handler's params.
+
+`/src/routes/user/=name.lisp` → `/user/:name`
