+  }

+### Settings configuration
+
+Define settings that apply globally or can be configured separately for each subreddit installation:
+
+```json
+{
+  "settings": {
+    "global": {
+      "featureEnabled": {
+        "type": "boolean",

+        "type": "paragraph",
+        "label": "Welcome message"
+      }
+    }
+  }
+}
+```
+
+At least one of `global` or `subreddit` is required. Supported setting types include strings, paragraphs, numbers, booleans, selects, and multi-selects. See [Settings and Secrets](../server/settings-and-secrets.mdx) for validation and access patterns.
+
+### Payments configuration
+
+The top-level `payments` object declares products and the internal endpoints used to fulfill or refund orders. It is separate from `permissions.payments`, which enables the payments plugin.
