+#### Which Options to Add In `setupOpts` {#sec-setupopts-which-options-to-add}
+
+For plugin modules that make use of the `setupOpts` pattern, try to keep the
+number of options you add to a minimum. You should only declare the options if
+one of these apply:
+
+1. The option is commonly used and complex enough that it would benefit from
+   additional documentation/checking, e.g., with an `example` field, advanced
+   type checking, or in the `description`.
+2. It is used by some other Nix module, usually for integration between
+   different plugins/modules.
+3. It is a path to some third-party program.
+4. Keymap options that plugins add by default, to document their default values.
+
+This is to minimize maintainer burden, since plugin options may have their type
+changed/extended or even removed/renamed entirely, after which we have to update
+on our side as well.
+
+Example, taken from the `fzf-lua` module:
+
+```nix
+{
+  options.vim.fzf-lua = {
+    enable = mkEnableOption "fzf-lua";
+    setupOpts = mkPluginSetupOption "fzf-lua" {
+      # 3rd case, program path
+      fzf_bin = mkOption {
+        type = str;
+        default = "${lib.getExe pkgs.fzf}";
+        example = "fzf"; # to get fzf from $PATH
+        description = "Path to fzf executable";
+      };
+      # 1st and 2nd case,
+      # 1. `borderType` is a custom type we defined in our lib that is shared
+      #    by other plugins
+      # 2. Integrates with the vim.ui.borders module
+      winopts.border = mkOption {
+        type = borderType;
+        default = config.vim.ui.borders.globalStyle;
+        defaultText = lib.literalExpression "config.vim.ui.borders.globalStyle";
+        description = "Border type for the fzf-lua picker window";
+      };
+    };
+  };
+};
+```
