you must create your own module, in method registerRoute(), register the necessary paths, install the module later.
class must be:
const MODULE_NAME = 'ModuleName';
and
protected static $loaded = false;

The module should be located in the modules/ModuleName folder.
Required files: Module.php -> extends App\Source\BaseModule,
info.json: https://github.com/andrey900/SlimCMS/blob/master/modules/Sections/info.json
config.json: https://github.com/andrey900/SlimCMS/blob/master/modules/Sections/config.json

You can use the module generator, it will create the necessary structure, and files, you will have to fill the registerRoute method only to install it. You can do this by enabled the options in the system: developersMode
