+<h3 id="how-do-i-update">How can I start using these new features?</h3>
+
+We got a few examples for making it easy to use these new feature, you can look the code snippet bellow
+
+```js
+// Before 2.8, we would use something like this
+export const removeByID = ({ id }) => {
+  SomeCollection.remove({ _id: id });
+};
+
+// Now we can also do like this
+export const removeByIDAsync = async ({ id }) => {
+  await SomeCollection.removeAsync({ _id: id });
+};
+
+Meteor.methods({
+   //...
+   removeByID,
+   removeByIDAsync,
+});
+
+// In UI use Meteor.call('removeByID', { id }) or Meteor.call('removeByIDAsync', { id })
+```
+
+More examples can be retrieved from [this commit](https://github.com/fredmaiaarantes/simpletasks/compare/main...mongodb-async-api).
