Support using Shaarli without URL rewriting

- Shaarli can be fully used by prefixing any URL with /index.php/
   - {$base_path} used in templates already works with this configuration
   - Assets path (outside of theme's assets) must be prefixed with {$root_url}/
   - Documentation section in « Server configuration »

Fixes #1590

 If Shaarli is hosted on a server behind a [reverse proxy](https://en.wikipedia.org/wiki/Reverse_proxy) (i.e. there is a proxy server between clients and the web server hosting Shaarli), configure it accordingly. See [Reverse proxy](Reverse-proxy.md) configuration.
 
+## Using Shaarli without URL rewriting
 
+By default, Shaarli uses Slim framework's URL, which requires
+URL rewriting.
+
+If you can't use URL rewriting for any reason (not supported by
+your web server, shared hosting, etc.), you *can* use Shaarli
+without URL rewriting.
+
+You just need to prefix your URL by `/index.php/`.
+Example: instead of accessing `https://shaarli.mydomain.org/`,
+use `https://shaarli.mydomain.org/index.php/`.
+
+**Recommended:**
+  * after installation, in the configuration page, set your header link to `/index.php/`.
+  * in you `config.json.php` set `general.root_url` to
+    `https://shaarli.mydomain.org/index.php/`.
