+# Coroutine Guide
+
+Starting from LeviLamina 1.0.0, coroutines replace the Scheduler.
+
+## Usage
+
+1. Include the header files:
+   ```cpp
+   #include "ll/api/chrono/GameChrono.h"
+   #include "ll/api/coro/CoroTask.h"
+   ```
+2. Call `ll::coro::keepThis` in a function, passing a lambda function that returns `ll::coro::CoroTask`.
+3. Call the `launch` or `syncLaunch` method after `keepThis`, the latter will block server thread, passing an `Executor`
+   class, such as `ll::thread::ServerThreadExecutor`.
+
+!!! tip "Available Executors"
+    `ll::thread::ServerThreadExecutor` (ll/api/thread/ServerThreadExecutor.h): Server thread
+    `ll::thread::ThreadPoolExecutor` (ll/api/thread/ThreadPoolExecutor.h): Thread pool  
+    For more Executors, refer to `ll/api/thread/`.
+
+## Examples
+
+### ServerThreadExecutor
+
+The following function uses a coroutine to print a string to the console every 20 ticks on the server thread, for a total of 20 times.
+
+```cpp
+#include "ll/api/chrono/GameChrono.h"
+#include "ll/api/coro/CoroTask.h"
+#include "ll/api/thread/ServerThreadExecutor.h"
+
+void createServerThreadCoro() {
+    using namespace ll::chrono_literals;
+    ll::coro::keepThis([]() -> ll::coro::CoroTask<> {
+        co_await 20_tick;
+        static int i = 0;
+        while (i < 20) {
+            std::cout << "This is coro in server thread\n";
+            ++i;
+        }
+        co_return;
+    }).launch(ll::thread::ServerThreadExecutor::getDefault());
+}
+```
+
+### ThreadPoolExecutor
+
+The following function uses a coroutine to print a string to the console every second in the thread pool, for a total of 20 times.
+
+```cpp
+#include "ll/api/chrono/GameChrono.h"
+#include "ll/api/coro/CoroTask.h"
+#include "ll/api/thread/ThreadPoolExecutor.h"
+
+void createServerThreadCoro() {
+    using namespace ll::chrono_literals;
+    ll::coro::keepThis([]() -> ll::coro::CoroTask<> {
+        co_await 1s;
+        static int i = 0;
+        while (i < 20) {
+            std::cout << "This is coro in server thread\n";
+            ++i;
+        }
+        co_return;
+    }).launch(ll::thread::ThreadPoolExecutor::getDefault());
+}
+```

+# 协程指南
+
+从LeviLamina 1.0.0开始，协程替代了Scheduler。
+
+## 用法
+
+1. 引用头文件
+   ```cpp
+   #include "ll/api/chrono/GameChrono.h"
+   #include "ll/api/coro/CoroTask.h"
+   ```
+2. 在函数中调用`ll::coro::keepThis`，传入返回值为`ll::coro::CoroTask`的lambda函数
+3. 在`keepThis`后调用`launch`或`syncLaunch`方法，后者会阻塞服务器线程，传入`Executor`类，比如
+   `ll::thread::ServerThreadExecutor`
+
+!!! tip "可用的Executor"
+    `ll::thread::ServerThreadExecutor`(ll/api/thread/ServerThreadExecutor.h): 服务器线程
+    `ll::thread::ThreadPoolExecutor`(ll/api/thread/ThreadPoolExecutor.h): 线程池  
+    更多Executor请参见`ll/api/thread/`
+
+## 示例
+
+### ServerThreadExecutor
+
+以下函数使用协程实现了在服务器线程每20 tick输出字符串到控制台1次，共计20次。
+
+```cpp
+#include "ll/api/chrono/GameChrono.h"
+#include "ll/api/coro/CoroTask.h"
+#include "ll/api/thread/ServerThreadExecutor.h"
+
+void createServerThreadCoro() {
+    using namespace ll::chrono_literals;
+    ll::coro::keepThis([]() -> ll::coro::CoroTask<> {
+        co_await 20_tick;
+        static int i = 0;
+        while (i < 20) {
+            std::cout << "This is coro in server thread\n";
+            ++i;
+        }
+        co_return;
+    }).launch(ll::thread::ServerThreadExecutor::getDefault());
+}
+```
+
+### ThreadPoolExecutor
+
+以下函数使用协程实现了在线程池中每秒输出字符串到控制台1次，共计20次。
+
+```cpp
+#include "ll/api/chrono/GameChrono.h"
+#include "ll/api/coro/CoroTask.h"
+#include "ll/api/thread/ThreadPoolExecutor.h"
+
+void createServerThreadCoro() {
+    using namespace ll::chrono_literals;
+    ll::coro::keepThis([]() -> ll::coro::CoroTask<> {
+        co_await 1s;
+        static int i = 0;
+        while (i < 20) {
+            std::cout << "This is coro in server thread\n";
+            ++i;
+        }
+        co_return;
+    }).launch(ll::thread::ThreadPoolExecutor::getDefault());
+}
+```
