 # Usage
 
-Dotkernel API can be installed independently or together with other applications in the Dotkernel suite, based on your business requirements.
+Dotkernel Admin can be installed independently or together with other applications in the Dotkernel suite, based on your business requirements.
 These components are designed to complement each other (out-of-box they are separate codebases):
 
 - **Dotkernel API** exposes the content to 3rd-party frontends or backends.
 - **Dotkernel Admin** (optional) manages the data (create, edit, delete).
 - **Dotkernel Queue** (optional) queue management microservice.
 
-A safe bet is to start with Dotkernel API and integrate it into your existing platform.
-The API can manage the access permissions to keep your data secure:
-
-- Admin-level users create and edit the data for your existing backend.
-- Regular users read the data for your frontend.
+You can start with Dotkernel Admin and integrate it into your existing platform.
+The Admin has built-in reports and graphs that can be configured and customized based on your needs.
 
 Later on you can add:
 
-- Dotkernel Admin for its simple table-based approach, its reports and graphs.
+- Dotkernel API to handle all data manipulation.
 - Dotkernel Queue for its asynchronous task processing.
