 Introduction
 ------------
 
-GPTimer (General Purpose Timer) is the driver of {IDF_TARGET_NAME} Timer Group peripheral. The hardware timer features high resolution and flexible alarm action. The behavior when the internal counter of a timer reaches a specific target value is called a timer alarm. When a timer alarms, a user registered per-timer callback would be called.

+General-purpose timers are typically used in the following scenarios:
 
-- Free running as a wall clock, fetching a high-resolution timestamp at any time and any places
-- Generate period alarms, trigger events periodically
-- Generate one-shot alarm, respond in target time
+- To run freely like a clock, providing high-resolution timestamps anytime and anywhere;
+- To generate periodic alarms that trigger events at regular intervals;
+- To generate one-shot alarms that respond at a specific target time.

 通用定时器
 =====================
 
+:link_to_translation:`en:[English]`

 简介
 -----------------
 
 通用定时器是 {IDF_TARGET_NAME} 定时器组外设的驱动程序。{IDF_TARGET_NAME} 硬件定时器分辨率高，具有灵活的报警功能。定时器内部计数器达到特定目标数值的行为被称为定时器报警。定时器报警时将调用用户注册的不同定时器回调函数。
 
 通用定时器通常在以下场景中使用：
 
--  如同挂钟一般自由运行，随时随地获取高分辨率时间戳；
--  生成周期性警报，定期触发事件；
--  生成一次性警报，在目标时间内响应。
