-The MINIMAL framework that does **not limit your project with its own rules**, has **no dependencies**, implements the **best practices** of popular MVC-frameworks, it **VERY fast** and **optimized** for all the innovations in **PHP 8.2** 🤟
+# MINIMAL
+The best code-to-utility framework
 
-Can be configured to work with **any database** `core::$session` and **any HTML template engine** `$this->view`
-*personally, i prefer **ArangoDB** and **Twig***
-
-## Nearest plans (first half of 2025)
-1. Add **middlewares** technology
-2. Route sorting in the router `router::sort()`
-3. Add trigger routes from within routes
-4. Think about adding asynchronous executions
-5. Write an article describing the principles of the framework
