 ## Managing System Packages with Flakes
 
 After the switch, we can manage the system using Flakes. One common requirement is installing packages. We have previously seen how to install packages using `environment.systemPackages` from the official `nixpkgs` repository.
 
-Now let's learn how to install packages from other sources using Flakes. This provides greater flexibility, particularly when it comes to specifying software versions. Let's use [Helix](https://github.com/helix-editor/helix) editor as an example.

 ## 通过 Flakes 来管理系统软件 {#manage-system-software-with-flakes}
 
 切换完毕后，我们就可以通过 Flakes 来管理系统了。管系统最常见的需求就是装软件，我们在前面已经见识过如何通过 `environment.systemPackages` 来安装 `pkgs` 中的包，这些包都来自官方的 nixpkgs 仓库。
