-## The autoload\_\*.php Files
+## Autoloading
 
-The three `autoload_*.php` files are not required, but recommended. They provide the following:
-
-- `autoload_classmap.php` should return an array classmap of class name/filename
-  pairs (with the filenames resolved via the `__DIR__` magic constant).
-- `autoload_function.php` should return a PHP callback that can be passed to
-  `spl_autoload_register()`. Typically, this callback should utilize the map
-  returned by `autoload_classmap.php`.
-- `autoload_register.php` should register a PHP callback (typically that
-  returned by `autoload_function.php` with `spl_autoload_register()`.
-
-The purpose of these three files is to provide reasonable default mechanisms for
-autoloading the classes contained in the module, thus providing a trivial way to
-consume the module without requiring laminas-modulemanager` (e.g., for use outside
-a Laminas application).
+Since version 3, laminas-modulemanager does not provide own autoloading mechanisms
+and instead relies on [Composer dependency manager](https://getcomposer.org/)
+to provide autoloading.

+# Upgrading to 3.0
+
+## Module autoloading
+
+laminas-modulemanager originates from before the Composer was created, where each
+framework had to provide its own autoloading implementation.
+Since then Composer became the de-facto standard in managing dependencies and
+autoloading for the php projects.
+In light of that, laminas-servicemanager removes ModuleLoader and autoload
+providers support in version 3.0 in favor of
+[Composer dependency manager](https://getcomposer.org/).
+
+### Application local modules
+
+Autoloading rules for application local modules should now be defined in
+application's composer.json
+
+Before:
+
+```php
+namespace Application;
+
+class Module
+{
+    public function getAutoloaderConfig()
+    {
+        return [
+            'Laminas\Loader\StandardAutoloader' => [
+                'namespaces' => [
+                    __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
+                ],
+            ],
+        ];
+    }
+}
+```
+
+and after:
+
+```json
+{
+    "name": "laminas/laminas-mvc-skeleton",
+    "description": "Laminas MVC Skeleton Application",
+    "type": "project",
+    ...
+    "autoload": {
+        "psr-4": {
+            "Application\\": "module/Application/src/"
+        }
+    },
+    "autoload-dev": {
+        "psr-4": {
+            "ApplicationTest\\": "module/Application/test/"
+        }
+    }
+}
+```
+
+[laminas-composer-autoloading](https://github.com/laminas/laminas-composer-autoloading)
+provides a handy tool to easily add and remove autoloading rules for local modules to
+application's composer.json
+
+After autoloading rules were updated, composer will need to update autoloader:
+
+```console
+$ composer dump-autoload
+```
+
+### Composer installed modules
+
+For composer installed modules, autoloading rules will be automatically picked
+by composer from the module's composer.json and no extra effort is needed:
+```json
+{
+    "name": "acme/my-module",
+    "description": "Module for use with laminas-mvc applications.",
+    "type": "library",
+    "require": {
+        "php": "^7.1"
+    },
+    "autoload": {
+        "psr-4": {
+            "Acme\\MyModule\\": "src/"
+        }
+    }
+}
+```
