 * [How to use Elasticsearch with Spring Data](https://reflectoring.io/springboot-elasticsearch/)
 
-In this blog, we will use Spring Data Elasticsearch to highlight the main capabilities of Elasticsearch - indexing of documents and searching and finally build a simple search application for searching products in a product inventory.
+This application code demonstrates use of indexing and search capabilities of Spring Data Elasticsearch in a simple search application used for searching products in a product inventory. The main steps for running the application are:
+
+1. Start an Elasticsearch Instance by running the Docker `run` command:
+
+```shell
+docker run -p 9200:9200 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.10.0
+```
+
+2. Clone the application and change the current directory to application root.
+3. Build the application with Maven 
+
+```shell
+mvn clean package
+```
+4. Start the application
+
+```shell
+java -jar target/<application>.jar
+
+```
+5. The productindex will be built during application start up.
+6. Access the application with URL: http://localhost:8080/search
+7. Start to input some characters in the search box(examples: toy, white shirt, jacket, etc), which will open an auto-complete box of maximum 5 suggestions.
+8. Complete the search text and click search button to see the search results.
