+URL rewriting
+=============
+
+Kanboard is able to work indifferently with url rewriting enabled or not.
+
+- Example of URL rewritten: `/board/123`
+- Otherwise: `?controller=board&action=show&project_id=123`
+
+If you use Kanboard with Apache and with the mode rewrite enabled, nice urls will be used automatically.
+
+URL Shortcuts
+-------------
+
+- Go to the task #123: **/t/123**
+- Go to the board of the project #2: **/b/2**
+- Go to the project calendar #5: **/c/5**
+- Go to the list view of the project #8: **/l/8**
+- Go to the project settings for the project id #42: **/p/42**
+
+Configuration
+-------------
+
+By default, Kanboard will check if the Apache mode rewrite is enabled.
+
+To avoid the automatic detection of url rewriting from the web server, you can enable this feature in your config file:
+
+```
+define('ENABLE_URL_REWRITE', true);
+```
+
+When this constant is at `true`:
+
+- URLs generated from command line tools will be also converted
+- If you use another web server than Apache, by example Nginx or Microsoft IIS, you have to configure yourself the url rewriting
+
+Note: Kanboard always fallback to old school urls when it's not configured, this configuration is optional.
