-# Spring-Data-ElasticSearch-Example
-An example to demonstrate how Spring Data ElasticSearch works
+# Spring Data ElasticSearch Example
+
+## Introduction
+
+This example demonstrates how to use Spring Data ElasticSearch to do simple CRUD operation.
+
+You can find the tutorial about this example at the below link:
+
+[https://blog.madadipouya.com](https://blog.madadipouya.com)
+
+For this example, a Book controller created that allows to do the following operations with ElasticSearch:
+
+- Get list of all books
+- Create a book
+- Update a book by Id
+- Delete a book by Id
+- Search for a book by ISBN
+
+
+## How to run
+
+The first thing to do is to start ElasticSearch. For that you can use the `docker-compose` file in this project
+and run it like this:
+
+```bash
+$ docker-compose -f docker-compose up -d
+``` 
+
+It brings ElasticSearch up on a single node cluster with the cluser name `elasticsearch`.
+
+Then you can run the application like below:
+
+```bash
+$ ./mvnw spring-boot:run
+```
+
+If your ElasticSearch URI is not `localhost` and/or the cluster name is different simply override one or both of the following environment variable:
+
+- `ES_URI`
+- `ES_CLUSTER_NAME`
+
+Once everything is up and running open the browser and go to [http://localhost:8080](http://localhost:8080). You should see Swagger to interact with.
