 ## Quick Start
 
-> To build the dependencies & the project, refer to [`BUILD-Windows.md`](BUILD-Windows.md) or [`BUILD-ubuntu.md`](BUILD-ubuntu.md)

 - `WebApp/bserv` contains the source code for `bserv`.
+
+
+### Hello, World!
+
+*This [example](examples/hello-world) shows how to use `bserv` to echo a json object `{"msg": "hello, world!"}` when requesting `localhost:8080/hello`.*
+
+`main.cpp`:
+```C++
+#include <bserv/common.hpp>
+#include <boost/json.hpp>
+boost::json::object hello()
+{
+        return {{"msg", "hello, world!"}};
+}
+int main()
+{
+        bserv::server_config config;
+        // config.set_port(8080);
+        bserv::server{config, {
+                bserv::make_path("/hello", &hello)
+        }};
+}
+```
+
+`CMakeLists.txt`:
+```
+cmake_minimum_required(VERSION 3.10)
+
+project(hello)
+
+set(CMAKE_CXX_STANDARD 17)
+set(CMAKE_CXX_STANDARD_REQUIRED ON)
+
+add_subdirectory(path/to/WebApp/bserv bserv)
+add_executable(main main.cpp)
+target_link_libraries(main PUBLIC bserv)
+```
+
+
+### Sample Project: `WebApp`
+
 - `WebApp/WebApp` is a sample project.
 - [`config-Windows.json`](config-Windows.json) and [`config-ubuntu.json`](config-ubuntu.json) are two sample config file for `WebApp`'s startup parameters. **It should be configured and renamed to `config.json` before you start `WebApp`.**
 - To use `WebApp`, you should setup the database as well.

 You can import the sample database:
