 ### Layout Hooks for the Blazor UI
 
+The **Layout Hook System** allows you to add code to some specific parts of the layout and all layout of the themes provided by the ABP Framework implement these hooks. 
+
+This system was already implemented for MVC UI but not for the Blazor UI and we've announced in the [ABP 6.0 Release Candidate blog-post](https://blog.abp.io/abp/ABP.IO-Platform-6.0-RC-Has-Been-Published) to we're planning to implement it in version 7.0.
+
+Now, we are introducing the Layout Hook System for Blazor UI as planned within this version. 
+
+> You can read the [Blazor UI: Layout Hooks](https://docs.abp.io/en/abp/7.0/UI/Blazor/Layout-Hooks) documentation if you want to use the Layout Hooks in your Blazor application and see the required configurations.
