+== Nix-shell shebangs
+
+You can use `nix-shell` to run scripts in arbitrary languages, providing
+the necessary dependencies. This is particularly convenient for
+standalone scripts because you don’t need to create a repo and write a
+separate `flake.nix`.
+
+The script should start with two ``shebang'' (`#!`) commands. The first
+should invoke `nix-shell`. The second should declares the scrpt
+interpreter and any dependencies. Here are some examples.
+
+=== A Bash script depending on a package in the nixpkgs repo.
+
+Script:
+
+[source,bash,linenums]
+....
+include::bash-with-nixpkg.sh[]
+....
+
+Output:
+
+....
+$# shebangs/bash-with-nixpkg.sh
+....
+
+=== A Python script depending on a package in the nixpkgs repo.
+
+Script:
+
+[source,bash,linenums]
+....
+include::python-with-nixpkg.sh[]
+....
+
+Output:

+....
+$# shebangs/python-with-nixpkg.sh
