 本程序随手写的，下面介绍也是随心写的，不喜勿碰。

 命令参数：
 
 ```shell
-./NeverIdle -c 2h -m 2 -n 4h
+./NeverIdle -cp 0.15 -m 2 -n 4h
 ```
 
 其中：
 
 -c 指启用 CPU 定期浪费，后面跟随每次浪费的间隔时间。  
-如每 12 小时 23 分钟 34 秒浪费一次，则为 12h23m34s。按照格式填。
+如每 12 小时 23 分钟 34 秒浪费一次，则为 `-c 12h23m34s`。按照格式填。
 
 -cp 指启用粗粒度的 CPU 百分比浪费，浪费率将随机器的使用水平实时变化。  
-如最大浪费20%的CPU，则为 -cp 0.2。百分比的取值范围 [0, 1] 并且注意不要和 `-c` 一起使用。

 -m 指启用浪费的内存量，后面是一个数字，单位为 GiB。  
 启动后会占用对应量的内存，并且保持不会释放，直到手动杀死进程。

+*I love you, but do not stop my machine, could you?*
+
+---
+
+**To non-Chinese users:**
+
+Thank you for liking this program! :-P  
+I invented this to share among my Chinese friends at first, but I didn't expect it to become popular in the world.  
+Also, I'm sorry for the late official English README! Now just enjoy it. :-D
+
+If you need help, Google first, and then go to the issue.
+I speak Chinese and English. For other languages, please translate before asking questions. :)
+
+---
+
+## Usage
+
+Download executable file from Release. Note the distinction between amd64 and arm64.
+
+Start a screen on the server and run it.
+If you want to learn about screen command, just Google.
+
+Command arguments：
+
+```shell
+./NeverIdle -cp 0.15 -m 2 -n 4h
+```
+
+In which:
+
+-c enables CPU periodic waste, followed by the interval between wastes.  
+E.g. waste CPU every 12 hours 23 minutes and 34 seconds, then the argument would be `-c 12h23m34s`.
+Just follow this template.
+
+-cp enables coarse-grained CPU percentage waste, and the waste rate will change in real time with the usage level of the machine.  
+If the maximum waste of 20% of the CPU is `-cp 0.2`. The value range of percentage is [0, 1] and be careful not to use it with `-c`.
+
+-m enables memory waste, followed by a number in GiB.  
+After startup, the specified amount of memory will be occupied and will not be released until the process is killed.
+
+-n enables network(bandwidth) periodic waste, followed by the interval between wastes.  
+Argument format is the same as `-c`. The Ookla Speed Test will be performed periodically (and the results will be output!)
+
+-t specifics the number of concurrent connections of the network periodic waste.  
+The default is 10. The larger the value, the more resources will be consumed. For most situations, it does not need to be changed.
+
+-p specifics the process priority, followed by a priority value. If not specified, the lowest priority of the platform will be used by default.  
+For UNIX-like systems (such as Linux, FreeBSD, and macOS), the value range is [-20,19], and the higher the number, the lower the priority.  
+For Windows, see [the official documentation](https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-setpriorityclass).  
+It is recommended not to specify because the default is the lowest priority, making way for all other processes.
+
+*All the functions you configured will be executed once immediately when you start the program, so you can take a look at the effect.*
