## `manifest.nix`
The manifest file records the provenance of the packages that are installed in a [profile](./profiles.md) managed by [`nix-env`](@docroot@/command-ref/nix-env.md).
Here is an example of how this file might look like after installing `hello` from Nixpkgs:
```nix

available = true;

"https://git.savannah.gnu.org/cgit/hello.git/plain/NEWS?h=v2.12.1";

It is fully customizable.

Each element in this list corresponds to an installed package.
It incorporates some attributes of the original derivation, including `meta`, `name`, `out`, `outPath`, `outputs`, `system`.
This information is used by Nix for querying and updating the package.
