       This should be disabled if manual setup is required or if auto-enabling

+
+    `autoEnableExpr` (String)
+    : A string representation of `autoEnable`, for use in documentation.
+
+      Not required if `autoEnable` is a literal `true` or `false`, but **must**
+      be used when `autoEnable` is a dynamic expression.
+
+      E.g. `"pkgs.stdenv.hostPlatform.isLinux"`.
+
+    `autoWrapEnableExpr` (Boolean)
+    : Whether to automatically wrap `autoEnableExpr` with parenthesis, when it
+      contains a potentially problematic infix.
+
+      The default (`true`) is inherited from `mkEnableTargetWith`.
+
+    `enableExample` (Boolean or literal expression)
+    : An example to include on the enable option. The default is calculated
+      automatically by `mkEnableTargetWith` and depends on `autoEnable` and
+      whether an `autoEnableExpr` is used.
+
     `extraOptions` (Attribute set)
     : Additional options to be added in the `stylix.targets.${name}` namespace
       along the `stylix.targets.${name}.enable` option.
