+Frédéric Guillot
+
+Installation with Composer
+--------------------------
+
+```bash
+composer require fguillot/json-rpc @stable
+```
+
+Examples
+--------
+
+### Server
+
+Callback binding:
+
+```php
+<?php
+
+use JsonRPC\Server;
+
+$server = new Server();
+$server->getProcedureHandler()
+    ->withCallback('addition', function ($a, $b) {
+        return $a + $b;
+    })
+    ->withCallback('random', function ($start, $end) {
+        return mt_rand($start, $end);
+    })
+;
+
+echo $server->execute();
+```
+
+Callback binding from array:
+
+```php
+<?php
+
+use JsonRPC\Server;
+
+$callbacks = array(
+    'getA' => function() { return 'A'; },
+    'getB' => function() { return 'B'; },
+    'getC' => function() { return 'C'; }
+);
+
+$server = new Server();
+$server->getProcedureHandler()->withCallbackArray($callbacks);
+
+echo $server->execute();
+```
+
+Class/Method binding:
+
+```php
+<?php
+
+use JsonRPC\Server;
+
+class Api
+{
+    public function doSomething($arg1, $arg2 = 3)
+    {
+        return $arg1 + $arg2;
+    }
+}
+
+$server = new Server();
+$procedureHandler = $server->getProcedureHandler();
+
+// Bind the method Api::doSomething() to the procedure myProcedure
+$procedureHandler->withClassAndMethod('myProcedure', 'Api', 'doSomething');
+
+// Use a class instance instead of the class name
+$procedureHandler->withClassAndMethod('mySecondProcedure', new Api, 'doSomething');
+
+// The procedure and the method are the same
+$procedureHandler->withClassAndMethod('doSomething', 'Api');
+
+// Attach the class, the client will be able to call directly Api::doSomething()
+$procedureHandler->withObject(new Api());
+
+echo $server->execute();
+```
+
+Class/Method binding from array:
+
+```php
+<?php
+
+use JsonRPC\Server;
+
+class MathApi
+{
+    public function addition($arg1, $arg2)
+    {
+        return $arg1 + $arg2;
+    }
+
+    public function subtraction($arg1, $arg2)
+    {
+        return $arg1 - $arg2;
+    }
+
+    public function multiplication($arg1, $arg2)
+    {
+        return $arg1 * $arg2;
+    }
+
+    public function division($arg1, $arg2)
+    {
+        return $arg1 / $arg2;
+    }
+}
+
+$callbacks = array(
+    'addition'       => array( 'MathApi', addition ),
+    'subtraction'    => array( 'MathApi', subtraction ),
+    'multiplication' => array( 'MathApi', multiplication ),
+    'division'       => array( 'MathApi', division )
+);
+
+$server = new Server();
+$server->getProcedureHandler()->withClassAndMethodArray($callbacks);
+
+echo $server->execute();
+```
+
+Server Middleware:
+
+Middleware might be used to authenticate and authorize the client.
+They are executed before each procedure.
+
+```php
+<?php
+
+use JsonRPC\Server;
+use JsonRPC\MiddlewareInterface;
+use JsonRPC\Exception\AuthenticationFailureException;
+
+class Api
+{
+    public function doSomething($arg1, $arg2 = 3)
+    {
+        return $arg1 + $arg2;
+    }
+}
+
+class MyMiddleware implements MiddlewareInterface
+{
+    public function execute($username, $password, $procedureName)
+    {
+        if ($username !== 'foobar') {
+            throw new AuthenticationFailureException('Wrong credentials!');
+        }
+    }
+}
+
+$server = new Server();
+$server->getMiddlewareHandler()->withMiddleware(new MyMiddleware());
+$server->getProcedureHandler()->withObject(new Api());
+echo $server->execute();
+```
+
+You can raise a `AuthenticationFailureException` when the API credentials are wrong or a `AccessDeniedException` when the user is not allowed to access to the procedure.
+
+### Client
+
+Example with positional parameters:
+
+```php
+<?php
+
+use JsonRPC\Client;
+
+$client = new Client('http://localhost/server.php');
+$result = $client->execute('addition', [3, 5]);
+```
+
+Example with named arguments:
+
+```php
+<?php
+
+use JsonRPC\Client;
+
+$client = new Client('http://localhost/server.php');
+$result = $client->execute('random', ['end' => 10, 'start' => 1]);
+```
+
+Arguments are called in the right order.
+
+Examples with the magic method `__call()`:
+
+```php
+<?php
+
+use JsonRPC\Client;
+
+$client = new Client('http://localhost/server.php');
+$result = $client->random(50, 100);
+```
+
+The example above use positional arguments for the request and this one use named arguments:
+
+```php
+$result = $client->random(['end' => 10, 'start' => 1]);
+```
+
+### Client batch requests
+
+Call several procedures in a single HTTP request:
+
+```php
+<?php
+
+use JsonRPC\Client;
+
+$client = new Client('http://localhost/server.php');
+
+$results = $client->batch()
+                  ->foo(['arg1' => 'bar'])
+                  ->random(1, 100)
+                  ->add(4, 3)
+                  ->execute('add', [2, 5])
+                  ->send();
+
+print_r($results);
+```
+
+All results are stored at the same position of the call.
+
+### Client exceptions
+
+Client exceptions are normally thrown when an error is returned by the server. You can change this behaviour by
+using the `$returnException` argument which causes exceptions to be returned. This can be extremely useful when
+executing the batch request. 
+
+- `BadFunctionCallException`: Procedure not found on the server
+- `InvalidArgumentException`: Wrong procedure arguments
+- `JsonRPC\Exception\AccessDeniedException`: Access denied
+- `JsonRPC\Exception\ConnectionFailureException`: Connection failure
+- `JsonRPC\Exception\ServerErrorException`: Internal server error
+
+### Enable client debugging
+
+You can enable the debug mode to see the JSON request and response:
+
+```php
+<?php
+
+use JsonRPC\Client;
+
+$client = new Client('http://localhost/server.php');
+$client->getHttpClient()->withDebug();
+```
+
+The debug output is sent to the PHP system logger.
+You can configure the log destination in your `php.ini`.
+
+Output example:
+
+```json
+==> Request:
+{
+    "jsonrpc": "2.0",
+    "method": "removeCategory",
+    "id": 486782327,
+    "params": [
+        1
+    ]
+}
+==> Response:
+{
+    "jsonrpc": "2.0",
+    "id": 486782327,
+    "result": true
+}
+```
+
+### IP based client restrictions
+
+The server can allow only some IP addresses:
+
+```php
+<?php
+
+use JsonRPC\Server;
+
+$server = new Server;
+
+// IP client restrictions
+$server->allowHosts(['192.168.0.1', '127.0.0.1']);
+
+[...]
+
+// Return the response to the client
+echo $server->execute();
+```
+
+If the client is blocked, you got a 403 Forbidden HTTP response.
+
+### HTTP Basic Authentication
+
+If you use HTTPS, you can allow client by using a username/password.
+
+```php
+<?php
+
+use JsonRPC\Server;
+
+$server = new Server;
+
+// List of users to allow
+$server->authentication(['user1' => 'password1', 'user2' => 'password2']);
+
+[...]
+
+// Return the response to the client
+echo $server->execute();
+```
+
+On the client, set credentials like that:
+
+```php
+<?php
+
+use JsonRPC\Client;
+
+$client = new Client('http://localhost/server.php');
+$client->getHttpClient()
+    ->withUsername('Foo')
+    ->withPassword('Bar');
+```
+
+If the authentication failed, the client throw a RuntimeException.
+
+Using an alternative authentication header:
+
+```php
+
+use JsonRPC\Server;
+
+$server = new Server();
+$server->setAuthenticationHeader('X-Authentication');
+$server->authentication(['myusername' => 'mypassword']);
+```
+
+The example above will use the HTTP header `X-Authentication` instead of the standard `Authorization: Basic [BASE64_CREDENTIALS]`.
+The username/password values need be encoded in base64: `base64_encode('username:password')`.
+
+### Local Exceptions
+
+By default, the server will relay all exceptions to the client.
+If you would like to relay only some of them, use the method `Server::withLocalException($exception)`:
+
+```php
+<?php
+
+use JsonRPC\Server;
+class MyException1 extends Exception {};
+class MyException2 extends Exception {};
+
+$server = new Server();
+
+// Exceptions that should NOT be relayed to the client, if they occurs
+$server
+    ->withLocalException('MyException1')
+    ->withLocalException('MyException2')
+;
+
+[...]
+
+echo $server->execute();
+```
+
+### Callback before client request
+
+You can use a callback to change the HTTP headers or the URL before to make the request to the server.
+
+Example:
+
+```php
+<?php
+
+$client = new Client();
+$client->getHttpClient()->withBeforeRequestCallback(function(HttpClient $client, $payload) {
+    $client->withHeaders(array('Content-Length: '.strlen($payload)));
+});
+
+$client->myProcedure(123);
+```
