-Routes beginning with:
+## Route Prefixes
 
-```text
-api/
-```
+Routes can be mapped to different source directories using prefixes.
 
-are loaded from:
-
-```text
-src/api/
-```
-
-Everything else is loaded from:
+By default:
 
 ```text
 src/views/pages/
 ```
 
+is used for normal pages.
+
+The router also supports configurable route prefixes:
+
+```php
+$route_bases = [
+    'api/' => ROOT . '/src/api',
+];
+```
+
+Example:
+
+```php
+'/api/users' => 'api/users.php',
+```
+
+loads:
+
+```text
+src/api/users.php
+```
+
+while:
+
+```php
+'/about' => 'about.php',
+```
+
+loads:
+
+```text
+src/views/pages/about.php
+```
+
+### Adding A New Route Type
+
+Create a new directory:
+
+```text
+src/docs/
+```
+
+Then add a prefix:
+
+```php
+$route_bases = [
+    'api/'  => ROOT . '/src/api',
+    'docs/' => ROOT . '/src/docs',
+];
+```
+
+Now:
+
+```php
+'/docs/getting-started' => 'docs/getting-started.php',
+```
+
+will load:
+
+```text
+src/docs/getting-started.php
+```
+
+No router changes required.
