## Conclusion
In this article, I've tried to explain how we can integrate [Telerik Blazor Component](https://www.telerik.com/blazor-ui) to our Blazor UI. ABP Framework designed as modular, so that it can work with any UI library/framework.
This article shows how we can use this workflow library within our ABP-based application. We will start with a couple of examples and then we will integrate the **Elsa Dashboard** (you can see it in the above gif) into our application to be able to design our workflows visually.
