+
+![alt tag](./example-min.png)
+
+## spotify-api-server
+
+For use Spotify API you need to take authorization token from Spotify.
+You can take authorization token from [Here](https://developer.spotify.com/web-api/console/get-search-item/)
+
+In the ```
+       application.yml
+       ```, you can set token here.
+
+This token looks like this;
+```
+token: "BQDYNZJKRPp271pXIiMRrRbx77TSo5BuQKMZeBXFlD9FwwRP4VjbkKxTfwKOvZSS_kZCQYSGK9QA7dKFl63tXo4taPItG6ya0AL-7L2zvOlI8IDrRwoF4yEws8AJjXtf2-PKJqj3hmaz765w_A"
+```
+
+The project is a Spring Boot project. For this reason, you can run the Application class by running it.
+
+## spotify-api-ui
+
+###### This module uses React and React-Bootstrap. Includes paging and limiting features about Spotify response.
+
+In the project folder ```
+                      $ cd spotify-api-ui
+                      ``` use the following command.
+```
+$ npm install
+```
+
+then
+
+```
+$ npm start
+```
+
+and project will start at ```
+                          http://127.0.0.1:3000
+                          ```
