+The kubectl completion script for Fish can be generated with the command `kubectl completion fish`. Sourcing the completion script in your shell enables kubectl autocompletion.
+
+To do so in all your shell sessions, add the following line to your `~/.config/fish/config.fish` file:
+-->
+kubectl 通过命令 `kubectl completion fish` 生成 Fish 自动补全脚本。
+在 shell 中导入（Sourcing）该自动补全脚本，将启动 kubectl 自动补全功能。
+
+为了在所有的 shell 会话中实现此功能，请将下面内容加入到文件 `~/.config/fish/config.fish` 中。
+
+```shell
+kubectl completion fish | source
+```
+
+<!--
+After reloading your shell, kubectl autocompletion should be working.
+-->
+重新加载 shell 后，kubectl 自动补全功能将立即生效。
