 This Provider is designed to allow the use of OpenFeature with Split, the platform for controlled rollouts, serving features to your users via the Split feature flag to manage your complete customer experience.
 
 ## Compatibility
+It supports **Node.js version 14.x or later**.
 
 
 ## Getting started
@@ -59,9 +60,40 @@ const context: EvaluationContext = {
   targetingKey: 'TARGETING_KEY',
 };
 OpenFeatureAPI.getInstance().setCtx(context)
-````
+```
 If the context was set at the client or api level, it is not required to provide it during flag evaluation.
 
+## Evaluate with details
+Use the get*Details(...) APIs to get the value and rich context (variant, reason, error code, metadata). This provider includes the Split treatment config as a raw JSON string under flagMetadata["config"]
+
+```js
+const booleanTreatment = await client.getBooleanDetails('boolFlag', false, context);
+
+const config = booleanTreatment.flagMetadata.config
+```
+
+## Tracking
+
+To use track(eventName, context, details) you must provide:
+
+- A non-blank `eventName`.
+- A context with:
+  - `targetingKey` (non-blank).
+  - `trafficType` (string, e.g. "user" or "account").
+
+Optional:
+
+- details with:
+  - `value`: numeric event value (defaults to 0).
+  - `properties`: map of attributes (prefer primitives: string/number/boolean/null).
+
+Example:
+```js
+const context = { targetingKey: 'user-123', trafficType: 'account' }
+const details = { value: 19.99, plan: 'pro', coupon: 'WELCOME10' }
+
+client.track('checkout.completed', context, details)
+```
