 # @examples/mf-react-component
 
 This example demonstrates how to use Rslib to build a simple Module Federation React component.
+
+### Usage
+
+Dev MF module
+
+1. Start remote module which is loaded by Rslib module.
+
+```
+nx run @examples/mf-remote:dev
+```
+
+2. Start MF dev mode.
+
+```
+nx run @examples/mf-react-component:dev
+```
+
+3. Use Storybook to development component.
+
+```
+nx run @examples/mf-react-component:storybook
+```
+
+Build
+
+```
+nx run @examples/mf-react-component:build
+```
+
+Build and Serve dist
+
+```
+nx run @examples/mf-react-component:serve
+```
