+Packages in CUE allow us to write _modular_, _reusable_, and _composable_ code. We can define schemas that are _imported_ into various files and projects. If you’ve written Go, then CUE should feel quite familiar. Not only is it [written in Go](https://pkg.go.dev/cuelang.org/go@v0.4.0/cue#pkg-overview) much of its behavior and syntax are modeled after Go as well.
 
-In the last few examples we've included an `import` statement to load the builtin `"strings"` package. If you've written Go then CUE should feel quite familiar. Not only is it [written in Go](https://pkg.go.dev/cuelang.org/go@v0.4.0/cue#pkg-overview) much of its behavior and syntax are modeled after Go as well.
+CUE has a number of [builtin packages](https://pkg.go.dev/cuelang.org/go/pkg) such as `strings`, `regexp`, `math`, and many more. These builtin packages are already available to CUE without the need to download or install anything else. Third-party packages are those that are placed within the `cue.mod/pkg/` folder and start with a fully qualified domain such as `alpha.dagger.io`.
