+  ## optionsCommonMark
+
+  Documentation in CommonMark text format.
+
+  ## optionsJSON
+
+  All options in a JSON format suitable for further automated processing.
+
+  `example.json`
+  ```json
+  {
+    ...
+    "fileSystems.<name>.options": {

+  ## optionsDocBook
+
+  deprecated since 23.11 and will be removed in 24.05.
+
+  ## optionsAsciiDoc
+
+  Documentation rendered as AsciiDoc. This is useful for e.g. man pages.
+
+  > Note: NixOS itself uses this ouput to to build the configuration.nix man page"
+
+  ## optionsNix
+
+  All options as a Nix attribute set value, with the same schema as `optionsJSON`.
+
+  # Example
+
+  ## Example: NixOS configuration
+
+  ```nix
+  let
+    # Evaluate a NixOS configuration
+    eval = import (pkgs.path + "/nixos/lib/eval-config.nix") {
+      # Overriden explicitly here, this would include all modules from NixOS otherwise.

+      ];
+    };
+  in
+    pkgs.nixosOptionsDoc {
+      inherit (eval) options;
     }
+  ```
+
+  ## Example: non-NixOS modules
+
+  `nixosOptionsDoc` can also be used to build documentation for non-NixOS modules.
 
+  ```nix
+  let
+    eval = lib.evalModules {
