-Unofficial recipe for FTXUI exists on Conan Center:
-<https://conan.io/center/recipes/ftxui>
+FTXUI can be easily obtained and integrated into your project using the Conan package manager.
+
+## Prerequisites
+
+First, ensure that Conan is installed on your system. If not, you can install it via pip:
+
+```powershell
+pip install conan
+```
+Conan often works in tandem with CMake, so you will need to have CMake installed as well. Once you have confirmed both Conan and CMake are installed, create a project directory, for example, `ftxui-demo`:
+
+```powershell
+mkdir C:\ftxui-demo
+cd C:\ftxui-demo
+```
+
+## Configuration
+
+After ensuring your environment is set up correctly, create a Conan configuration file `conanfile.txt`. This file is used to declare your project's dependencies. The community-maintained package for FTXUI can be found on [Conan Center](https://conan.io/center/recipes/ftxui).
 
 > [!note]
-> This is an unofficial recipe. That means it is not maintained by the FTXUI
-> team, but by the community. The package maintainers seems to actively update
-> the package to the latest version. Thanks to the maintainers for their work!
+> This is an unofficial build script. This means it is not maintained by the FTXUI
+> team but by the community. The package maintainer appears to actively update it
+> to the latest releases. Many thanks to the maintainer for their work!
 
+@todo If you are familiar with the process, please consider adding an "official" build script to Conan Center.
+This could be a GitHub Action that automatically updates Conan Center upon new releases.
 
-@todo Add instructions on how to use the conan recipe.
+```ini
+[requires]
+ftxui/6.0.2
 
-@todo Please consider adding an "official" recipe to Conan Center if know how.
-It could be a github action that will automatically update the conan center
-when a new release is made.
+[generators]
+CMakeDeps
+CMakeToolchain
+
+[layout]
+cmake_layout
+```
+
+## Install Dependencies and Build
+
+Once configured, run the following command to install FTXUI and its dependencies:
+
+```powershell
+conan install . --output-folder=build --build=missing
+```
+
+This will download and install `ftxui/6.0.2` along with all its dependencies from Conan's remote repositories.
+
+After the installation completes, you can test it by creating a `demo.cpp` file in your project directory:
+
+```cpp
+#include <ftxui/screen/screen.hpp>
+#include <ftxui/dom/elements.hpp>
+#include <iostream>
+
+int main() {
+    using namespace ftxui;
+    auto document = hbox({
+        text(" Hello "),
+        text("FTXUI ") | bold | color(Color::Red),
+        text(" world! ")
+    });
+    auto screen = Screen::Create(Dimension::Full(), Dimension::Fit(document));
+    Render(screen, document);
+    std::cout << screen.ToString() << std::endl;
+    return 0;
+}
+```
+
+If the test is successful, you can then create a `CMakeLists.txt` file in the project directory:
+
+```cmake
+cmake_minimum_required(VERSION 3.20)
+project(ftxui-demo)
+
+# Set the C++ standard
+set(CMAKE_CXX_STANDARD 20)
+
+# Find the FTXUI package installed via Conan
+find_package(ftxui CONFIG REQUIRED)
+
+# Create the executable
+add_executable(demo demo.cpp)
+
+# Link the executable to the FTXUI library
+target_link_libraries(demo PRIVATE ftxui::component)
+```
+
+@todo 考虑到中国多数地区使用Conan很有可能遇到各种网络问题，我想做一个定制的版本说明，但是我对conan的了解有限再加上没有找到合适的资料，因此这个计划短暂的被搁置了，如果您知道方法，欢迎在[中文版本](xiaoditx.girhub.io/public/docs/ftxui%E4%B8%AD%E6%96%87%E7%BF%BB%E8%AF%91/installation/conan/)的下方留下评论以提醒我
