+In the example above, we aim to encapsulate that the drop cap should be disabled globally but enabled in the paragraph context. The drop cap in the Image block context wouldn't make sense based on the current implementation so would be ignored, but it could be used by plugins that extend its functionality.

 ### Features
 
-This is being implemented, so it's not currently available.
+So far, this function is only enabled for the `global` section in `experimental-theme.json`.
+
+```
+{
+  "global": {
+    "features": {
+      "typography": {
+        "dropCap": false
+			}
+		}
+	}
+}
+```
+
+Then each block can decide to override how they handle block editor features during their registration process (`register_block_type` or `registerBlockType` calls) using `supports` object in `block.json` file:
+
+```
+{
+  "supports": {
+    "__experimentalFeatures": {
+      "typography": {
+        "dropCap": true
+			}
+		}
+  }
+}
+```
+
+Moving forward, we plan to integrate overrides targeting individual blocks defined inside `experimental-theme.json` file that would be applied on top of features defined by block authors in `supports` property.
+
+Finally, this is how it can be used in the block's `edit` implementation:
+
+```js
+// edit.js
+
+const Edit = ( props ) => {
+    const isDisabled = ! useEditorFeature( 'typography.dropCap', false );
+    // ...
+};
+```

+The list of features that are currently supported are:
