 # Building a REST API with Nitric
 
-This guide will show you how to build a serverless REST API with the Nitric framework using Dart. The example API enables reading, writing and editing basic user profile information using a Nitric [collection](https://nitric.io/docs/collections) to store user data. Once the API is created we'll test it locally, then optionally deploy it to a cloud of your choice.
