-# Introduction
+# Examples
 
-Xapi-cpp is a C++ library that provides a simple and easy-to-use API for interacting with the xStation5 trading platform.
-Built on top of the Boost libraries, it leverages Boost’s powerful and widely adopted capabilities, particularly for network-based applications. Boost provides robust, high-performance abstractions that simplify the development of complex asynchronous operations, making it an ideal choice for ensuring a reliable and efficient connection to the xStation5 platform.
-
-## Key Concepts
-
-### 1. Asynchronous Programming with Coroutines
-The library makes heavy use of C++20 coroutines and Boost.Asio to handle asynchronous operations. Each API call is suspended until the operation completes, allowing the program to remain responsive and efficient.
-
-While C++20 provides the coroutine syntax (``co_await``, ``co_return``, ``co_yield``), it doesn’t define a complete framework for asynchronous execution or I/O. Libraries like Boost.Asio provide the necessary abstractions and asynchronous I/O handling that C++20 coroutines on their own do not.
-
-### 2. Secure WebSocket Communication
-The xapi uses secure WebSockets (WebSockets over SSL) for communication, ensuring that the data transmitted between the client and server is encrypted. This provides a secure channel for sensitive information, such as account credentials and balance data.
-
-### 3. Separate WebSocket Connections
-The xapi establishes separate WebSocket connections for **xapi::Socket** and **xapi::Stream**. This separation aims to minimize congestion on a single connection especially if one connection is handling high-frequency data (like streaming).
-
-
-# Getting Started
-Let`s break down some important steps to start using xStation in your project
-
-## Awailable operations
-### 1. Socket Operations
-The **xapi::Socket** object is used to Request-Reply commands. Full list of commands is in [xApi Retrieving Trading Data](http://developers.xstore.pro/documentation/2.5.0#retrieving-trading-data)
-
-### 2. Stream Operations
-The **xapi::Stream** object is used to manage real-time streaming data, such as balance updates, tick prises and so on. Full list of streaming operations is in [xApi Available Streaming Commands](http://developers.xstore.pro/documentation/2.5.0#available-streaming-commands)
-
-Please note, that to use streaming operations, you first should get streaming id from **xapi::Socket** login() command.
-
-## Cmake configuration
-Xapi supports ``find_package``, simplifying the process of linking the library to your project. A typical CMake configuration might look like this:
-
-```cmake
-    cmake_minimum_required(VERSION 3.10)
-    project(ExampleApp)
-
-    set(CMAKE_CXX_STANDARD 20)
-    set(CMAKE_CXX_STANDARD_REQUIRED ON)
-
-    find_package(Xapi REQUIRED)
-
-    add_executable(ExampleApp main.cpp)
-
-    target_link_libraries(ExampleApp
-        PRIVATE
-        Boost::system
-        Boost::json
-        Xapi::Xapi
-    )
-```
-
-
-## Simple example
-The simplest example is [RetrieveStreamSessionId](RetrieveStreamSessionId.cpp), which demonstrates how to connect to an xStation server using Xapi. The program initializes a session, logs in, and retrieves a stream session ID.
-
-Additional examples can be found in the .cpp files within the examples folder.
+This directory contains example implementations showcasing various scenarios where the library's features can be used.
 
 ## Compile examples
 You can compile all examples by following these steps:
 
 1. Fix your credentials in the example you want to use. In ``run`` function:
 
     ```cpp
-    const std::string accountId = "<your accountId>";
-    const std::string password = "<your password>";
+    const boost::json::object accountCredentials = {
+        {"accountId", "<your accountId>"},
+        {"password", "<your password>"},
+        {"accountType", "demo"} // If you are using real account, replace with "real"
+    };
 
-    // If you are using real account, replace with "real"
-    const std::string accountType = "demo";
     ```
