+# Configuration
+
+The default configuration file is located in `MODPATH/auth/config/auth.php`. You should copy this file to `APPPATH/config/auth.php` and make changes there, in keeping with the [cascading filesystem](../kohana/files).
+
+[Config merging](../kohana/config#config-merging) allows these default configuration settings to apply if you don't overwrite them in your application configuration file.
+
+Name | Type | Default | Description
+-----|------|---------|------------
+driver | `string` | file | The name of the auth driver to use.
+hash_method | `string` | sha256 | The hashing function to use on the passwords.
+hash_key | `string` | NULL | The key to use when hashing the password.
+session_type | `string` | [Session::$default] | The type of session to use when storing the auth user.
+session_key | `string` | auth_user | The name of the session variable used to save the user.

+# Developing Drivers
+
+## Real World Example
+
+Sometimes the best way to learn is to jump right in and read the code from another module. The [ORM](https://github.com/kohana/orm/blob/3.2/develop/classes/kohana/auth/orm.php) module comes with an auth driver you can learn from.
+
+[!!] We will be developing an `example` driver. In your own driver you will substitute `example` with your driver name.
+
+This example file would be saved at `APPPATH/classes/auth/example.php` (or `MODPATH` if you are creating a module).
+
+---
+
+## Quick Example
+
+First we will show you a quick example and then break down what is going on.
+
+~~~
+class Auth_Example extends Auth
+{
+	protected function _login($username, $password, $remember)
+	{
+		// Do username/password check here
+	}
+
+	public function password($username)
+	{
+		// Return the password for the username
+	}
+
+	public function check_password($password)
+	{
+		// Check to see if the logged in user has the given password
+	}
+
+	public function logged_in($role = NULL)
+	{
+		// Check to see if the user is logged in, and if $role is set, has all roles
+	}
+
+	public function get_user($default = NULL)
+	{
+		// Get the logged in user, or return the $default if a user is not found
+	}
+}
+~~~
+
+## Extending Auth
+
+All drivers must extend the [Auth] class.
+
+	class Auth_Example extends Auth
+
+## Abstract Methods
+
+The `Auth` class has 3 abstract methods that must be defined in your new driver.
+
+~~~
+abstract protected function _login($username, $password, $remember);
+
+abstract public function password($username);
+
+abstract public function check_password($user);
+~~~
+
+## Extending Functionality
+
+Given that every auth system is going to check if users exist and if they have roles or not you will more than likely have to change some default functionality.
+
+Here are a few functions that you should pay attention to.
+
+~~~
+public function logged_in($role = NULL)
+
+public function get_user($default = NULL)
+~~~
+
+## Activating the Driver
+
+After you create your driver you will want to use it. It is a easy as setting the `driver` [configuration](config) option to the name of your driver (in our case `example`).

+# File Driver
+
+The [Auth::File] driver is included with the auth module.
+
+Below are additional configuration options that can be set for this driver.
+
+Name | Type | Default | Description
+-----|------|---------|-------------
+users | `array` | array() | A user => password (_hashed_) array of all the users in your application
+
+## Forcing Login
+
+[Auth_File::force_login] allows you to force a user login without a password.
+
+~~~
+// Force the user with a username of admin to be logged into your application
+Auth::instance()->force_login('admin');
+$user = Auth::instance()->get_user();

+# Auth
+
+User authentication and authorization is provided by the auth module.
+
+The auth module is included with Kohana, but needs to be enabled before you can use it. To enable, open your `application/bootstrap.php` file and modify the call to [Kohana::modules] by including the auth module like so:
+
+~~~
+Kohana::modules(array(
+	...
+	'auth' => MODPATH.'auth',
+	...
+));
+~~~
+
+Next, you will then need to [configure](config) the auth module.
+
+The auth module provides the [Auth::File] driver for you. There is also an auth driver included with the ORM module.
+
+As your application needs change you may need to find another driver or [develop](driver/develop) your own.

+# Log in and out
+
+The auth module provides methods to help you log users in and out of your application.
+
+## Log in
+
+The [Auth::login] method handles the login.
+
+~~~
+// Handled from a form with inputs with names email / password
+$post = $this->request->post();
+$success = Auth::instance()->login($post['email'], $post['password']);
+
+if ($success)
+{
+	// Login successful, send to app
+}
+else
+{
+	// Login failed, send back to form with error message
+}
+~~~
+
+## Logged in User
+
+There are two ways to check if a user is logged in. If you just need to check if the user is logged in use [Auth::logged_in].
+
+~~~
+if (Auth::instance()->logged_in())
+{
+	// User is logged in, continue on
+}
+else
+{
+	// User isn't logged in, redirect to the login form.
+}
+~~~
+
+You can also get the logged in user object by using [Auth::get_user]. If the user is null, then no user was found.
+
+~~~
+$user = Auth::instance()->get_user();
+
+// Check for a user (NULL if not user is found)
+if ($user !== null)
+{
+	 // User is found, continue on
+}
+else
+{
+	// User was not found, redirect to the login form
+}
+~~~
+
+## Log out
+
+The [Auth::logout] method will take care of logging out a user.
+
+~~~
+Auth::instance()->logout();
+// Redirect the user back to login page
+~~~
