# Adding Custom Packages {#sec-custom-packages}
It's possible that a package you need is not available in NixOS. In that
case, you can do two things. First, you can clone the Nixpkgs
repository, add the package to your clone, and (optionally) submit a
patch or pull request to have it accepted into the main Nixpkgs repository.
This is described in detail in the [Nixpkgs manual](https://nixos.org/nixpkgs/manual).
In short, you clone Nixpkgs:
case, you can do two things. Either you can package it with Nix, or you can try
to use prebuilt packages from upstream. Due to the peculiarities of NixOS, it
is important to note that building software from source is often easier than
using pre-built executables.
## Building with Nix {#sec-custom-packages-nix}
This can be done either in-tree or out-of-tree. For an in-tree build, you can
clone the Nixpkgs repository, add the package to your clone, and (optionally)
submit a patch or pull request to have it accepted into the main Nixpkgs
repository. This is described in detail in the [Nixpkgs
manual](https://nixos.org/nixpkgs/manual). In short, you clone Nixpkgs:
```ShellSession
$ git clone https://github.com/NixOS/nixpkgs

$ ./result/bin/hello
Hello, world!
```
## Using pre-built executables {#sec-custom-packages-prebuilt}
Most pre-built executables will not work on NixOS. There are two notable
exceptions: flatpaks and AppImages. For flatpaks see the [dedicated
section](#module-services-flatpak). AppImages will not run "as-is" on NixOS.
First you need to install `appimage-run`: add to `/etc/nixos/configuration.nix`
```nix
environment.systemPackages = [ pkgs.appimage-run ];
```
Then instead of running the AppImage "as-is", run `appimage-run foo.appimage`.
To make other pre-built executables work on NixOS, you need to package them
with Nix and special helpers like `autoPatchelfHook` or `buildFHSUserEnv`. See
the [Nixpkgs manual](https://nixos.org/nixpkgs/manual) for details. This
is complex and often doing a source build is easier.
