+KeyClicker is an app that brings users a true keyboard typing sound experience, recreating the typing feel of mechanical keyboards and typewriters.
 
 If you are a writer or have a fondness for the sound of typewriters, KeyClicker will be your ideal choice. Many writers believe that the sound of a typewriter helps them focus more and inspires their creativity. While the charm of a physical typewriter is unique, it lacks the convenient features of modern devices, such as efficient editing and digital operations. With KeyClicker, you can enjoy the classic sound of a typewriter while retaining the powerful editing and publishing capabilities of macOS devices.
 
 If you are a programmer, KeyClicker can also bring you the ultimate experience of typing on a mechanical keyboard, making every keystroke immersive, enhancing your focus and enjoyment while coding!

+## Frequently Asked Questions
+
+### System Sound Overlap Issue
+
+If you hear two key sounds after setting the key sound, it may be because the system's default sound overlaps with the custom key sound. To solve this problem, you can go to `System Settings` -> `Sound` and turn off the two options: `Play user interface sound effects` and `Play feedback when volume is changed`, to avoid interference between the system sound and the custom sound.

+## 常见问题解答
+
+### 系统声音重叠问题
+
+如果您在设置按键声音后听到两个按键音，可能是因为系统默认的声音与自定义按键声音重叠。为了解决这个问题，您可以在 `系统设置` -> `声音` 中关闭 `播放用户界面音效` 和 `音量调整时播放反馈音效` 这两个选项，从而避免系统声音与自定义声音干扰。
