-### each path
+### classes
 Each module's implementation is represented as a **file** so as a **class** located in `/build/api/module/`. In order for the autoloader to work, you must name the **file** the same name as the **class**.
+Also the **namespace** must match, it corresponds to the path (starting at `/api`).
 
-### Method implementation
-Each method is represented as a method in its module's class.
+For instance if you have in your configuration a path called `/uri1/uri2/uri3`, you will create the file `/build/api/module/uri1/uri2/uri3.php`.
 
-### Input arguments
 
-Arguments are passed to the method as a single argument which an associative array according to the documentation.

-Creates a new `Request` object, you must give it a path following the pattern "module/method", the params must be an associative array. Note that the path can be inside the `$params` variable.
-
-It checks missing params and each needed params' type according to the **Checker** implementation (cf. [Checker](#4-checker)). It also checks the permissions you have according to the **AuthSystem** implementation (cf. [AuthSystem](#1-permissions--authsystem)).
+For instance here, we manage the call `GET /article/2` where `2` is the argument `URL0` renamed to `id_article`.
 
 ```php
-<?php
-	public function __construct(String $path, Array $params) : Request;
+use \error\core\Error;
+use \error\core\Err;
+
+
+public function GET($parameters){
+
+	/* (1) Set parameters available in the method scope */

+
+	/* (2) You can now use the variable `id_article` */
+	$article_data = get_article_from_database($id_article);
+
+	/* (3) Return error if error in process */
+	if( has_error($article_data) )
+		return [ 'error' => new Error(Err::ModuleError, 'Cannot fetch data from db.') ];
+
+
+	/* (4) Return data on success */
+	return [
+		'id_article' => $id_article,
+		'article' => $article_data
+	];

 ```
 
-Creates a new `Request` object but from the URL. It will seek for the *path* in the URL, then in the data. (it will call itself the **\_\_construct()** method).
-
-```php
-<?php
-	public static function remote(String $url, Array $data) : Request;
-```
-
-Registers the **AuthSystem** you want, must be done before any construction.
-
-```php
-<?php
-	public static function setAuthSystem(Request $instance) : bool;
-```
-
-Executes the current `Request` object and returns a `Response` object.
-```php
-<?php
-	public function dispatch() : Response;
-```
-
-Same as `dispatch()` but manages the **download** option (cf. [Configuration](#iii-configuration)). It will use 2 of the parameters you must return on success : `body`, and `headers`. The first one must contain the content of the file to create, the second the headers in an associative array.
-
-The call will become the file itself.
-
-Note: If the `HTTP_X_REQUESTED_WITH` header is present, it will create the downloadable file as **/tmp/download_{some\_hash}** and return a normal `Response` object with the field `link` containing the file absolute path.
-
-```php
-<?php
-	public function download() : null;
-	public function download() : Response; // if called by Ajax
-```

-### Attributes
-
-The attribute `error` will contain the current `Error` instance.
-
-```php
-<?php

-
-### Methods
-
-Returns an associative array containing the whole response data (excluding the error).
-
-```php
-<?php
-	public function getAll() : Array;
-```
-
-Returns only the field from the response data (if it exists).
-```php
-<?php
-	public function get(String $key) : mixed; // on success
-	public function get(String $key) : null;  // on error
-```
-
-Sets the `HTTP_CODE` according to the `Error` argument, also it sets the header for **application/json**.
-
-It can be used for simple API response, it will add the *"error"* and *"ErrorDescription"* fields to the data and set the headers so you can display the result of the API call.
-
-```php
-<?php
-	public function serialize() : String;
-```
