 #### 2. Project's file structure
 xdrm-framework is based on `all is in config` so you will have this structure :
-- folder `build` which contains framework's modules.
-- folder `public_html` which contains visible content.
-- folder `config` which contains the modules' config files.
+- folder `build` which contains framework's modules (core + data).
+- folder `public_html` which contains visible content (html, css, js).
+- folder `config` which contains the modules' config files (mainly json).
 - file `autoloader.php` which will auto-load the components.
 
 **Note:** In every php file you want to use framework's classes, you have to begin your file by :
 ```php
 <?php
-      /* [1] dirname() as long as you're not at the project's root */
-      define('__ROOT__', dirname(dirname(__FILE__))); 
-      require_once __ROOT__.'/autoloader.php';
+      /* [1] load the autoloader with correct path */
+      require_once '../autoloader.php';
       
       /* [2] then you can load your classes */
-      use api\core\ModuleRequest;
-      use error\core\Error;
+      use api\core\Request;  // ex1: api request manager
+      use error\core\Error;  // ex2: error manager
+      use error\core\Err;    // ex3: error codes
       
       /* [3] and use them as long as you want without namespace */
-      $request  = new ModuleRequest('module/method', ['id_user' => 10]);

+#### [3.1] API - self-managed API
+
+###### How to use
+In order to use the API, you must begin by writting your _"methods"_ in the configuration file located at `/config/modules.json`.
+In order to be understood, lets call `module` a group of methods, and `method` a function which outputs data from input parameters.
+
+
+**Configuration format**
+```json
+{
+
+    "{module_name}": {
+        
+        "{http_method}::{method_name}": {
+            "description": "{method_description}",
+            "permissions": ["{perm}"],
+            "options": { "download": {is_download} },
+            "parameters: {
+                "{name_param}": { "description": "{desc_param}", "type": "{type_param}", "optional": {is_optional} }
+            },
+            "output": {
+                "{name_output}": { "description": "{desc_output}", "type": "{type_output}" }
+            }
+        }
+        
+        
+    }
+}
+
+```
+
+
+###### Classes (advanced)
+The API is managed through 5 classes :
+1. Request   - is the core of the module
+2. Response  - renders and manages the responses
+3. Authentification - manages the authentification part (it has to be over written for each case)
+4. Checker - manages auto checked parameters' types
+5. ModuleFactory - to instanciate each module, transparent to the user

 #### [3.2] error - error system
 #### [3.3] database - database wrapper and repository manager
 #### [3.4] orm - sql orm
