+| configured with a bunch of paths:
+|
+| - The *base path* is Flarum's root directory and contains important files
+|   such as config.php and extend.php.
+| - The *public path* is the directory that serves as document root for the
+|   web server. Files in this place are accessible to the public internet.
+|   This is where assets such as JavaScript files or CSS stylesheets need to
+|   be stored in a default install.
+| - The *storage path* is a place for Flarum to store files it generates during
+|   runtime. This could be caches, session data or other temporary files.
+|
+| The fully configured site instance is returned to the including script, which
+| then uses it to boot up the Flarum application and e.g. accept web requests.
