 ## Step 1: Upgrade to EmberData 4.12.x
 
-This version of EmberData is the first version that supports the new APIs. It also a LTS version, so you can stay on it for a while. You can refer the [EmberData Compatibility table](https://github.com/emberjs/data/blob/main/README.md#compatibility) to see which version of EmberData is compatible with your Ember version.

-3. Lastly `Fetch`. It is a handler that is responsible for sending requests to the server using the new Ember Data APIs. It must be last handler you put in the chain. After finishing request it will enrich handlers context with `response` property. And pass it back to the handlers chain in reverse order. So `TestHandler` will receive `response` property first, and so on if we would have any.
+3. Lastly `Fetch`. It is a handler that sends requests to the server using the `fetch` API. It expects responses to be JSON and when in use it should be the last handler you put in the chain. After finishing each request it will convert the response into json and pass it back to the handlers chain in reverse order as the request context's response. So `TestHandler` will receive `response` property first, and so on if we would have any.
 
 You can read more about request manager in the [request manager guide](./request-manager-guide.md).
 
 ## Step 4: Install `@ember-data/json-api`, `@ember-data/request-utils` packages
 
-If you was using JSON:API adapter/serializer for your backend communication, you can use `@ember-data/json-api` package. It is a package that contains predefined builders for JSON:API requests. You can read more about it in the [`@ember-data/json-api` guide](TODO: add link).
