+`lunar-birthday-ical` reads a YAML configuration file and generates an iCalendar `.ics` file. Optionally, it can upload the calendar to pastebin for easy subscription. For an example configuration file, refer to [config/example-lunar-birthday.yaml](https://github.com/ak1ra-lab/lunar-birthday-ical/blob/master/config/example-lunar-birthday.yaml). The comments should be sufficient to explain the meaning of each option.
 
-可以使用 `-h` 或者 `--help` 选项查看命令行工具帮助信息,
+You can use the `-h` or `--help` option to view the command-line tool's help information.

-## 关于 pastebin
-
-在 YAML 配置文件中可选配置是否同时将生成的 `.ics` 文件同时上传 pastebin, 该 pastebin 实例是 repo owner 运行的一个基于 Cloudflare worker 的 pastebin 服务, 实例所使用的代码是 [SharzyL/pastebin-worker](https://github.com/SharzyL/pastebin-worker).
+## About pastebin
 
-如果选择启用 pastebin (`pastebin.enabled`), 在初次执行时, 可以保持 YAML 配置文件中的 `pastebin.name` 和 `pastebin.password` 为空, 命令执行时会自动上传, 上传成功后可以将标准输出中 `lunar_birthday_ical.pastebin` 日志行的 admin 中由 `:` 分隔的 `{{ pastebin.name }}` 和 `{{ pastebin.password }}` 手动填入配置文件, 这样下次再执行时就只会在原本的 URL 上更新, 而不会重新上传, 保持 URL 不变, 避免需要更新订阅日历的链接.
+In the YAML configuration file, you can choose whether to upload the generated `.ics` file to pastebin. This pastebin instance is a Cloudflare worker-based pastebin service ([SharzyL/pastebin-worker](https://github.com/SharzyL/pastebin-worker)) run by the repository owner.
 
-下方为启用 `pastebin.enabled` 后的命令行输出,
+If pastebin (`pastebin.enabled`) is enabled, you can leave `pastebin.name` and `pastebin.password` in the YAML configuration file empty on the first run. After executing the command, it will automatically upload, and upon successful upload, retrieve the `pastebin.name` and `pastebin.password` from the `admin` field in the `lunar_birthday_ical.pastebin` log line in the standard output (`pastebin.name` and `pastebin.password` are split with `:`, as shown in the output below with `XXXXXXXXXXXXXXXXXXXXXXXX` and `YYYYYYYYYYYYYYYYYYYYYYYY`). Manually fill these into the configuration file. This way, on subsequent executions, it will only update the existing URL instead of re-uploading, thus keeping the URL unchanged and avoiding the need to update the calendar URL.
