+# API-Builder Elasticsearch Connector
+
+Integrate Elasticsearch information into your [API-Builder flow][1] using this connector. 
+
+## Configuration
+
+After installation and restarting your API-Builder project you get the following new flow-nodes:  
+![Node][img1]   
+Before you can make use it in your flow you have to configure your Elasticsearch instance in your API-Builder project.
+
+During installation a new config file has been automatically created which must be completed with your Elasticsearch instance. You can do that directly from within the API-Builder UI:  
+![Config][img3]  
+We recommend to setup your configuration in a [environmentalized][4] way keeping [sensitive information][5] away from the source-code repository.
+
+## Elasticsearch
+This Connector is based on the https://www.elastic.co/blog/new-elasticsearch-javascript-client-released project. It's a good starting point to understand the APIs and their parameters reading the following documentation:   
+
+- [Introduction](https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/7.x/introduction.html)
+
+As of today, the flow node only supports the [search API](https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/7.x/api-reference.html#_search) described here:
+
+## Tests
+The project is mocking an Elastic-Search instance to execute tests and validate parameters and responses are handled correclty.
+And run the following command:  
+`npm test`  
+The tests are also automatically executed on every commit to this project.  
+
+## Compatibility
+Tested with Elasticsearch 7.4.0  
+Requires API-Builder Independence or higher
+
+## Changelog
+- 1.0.0 - 13.03.2020
+  - Initial version
+
+## Limitations/Caveats
+Only the search API is currently supported
+Authentication to the Elasticsearch instance is currently not supported
+
+If you require on the of the unsupported APIs or authentication don't hestitate to create an [issue][3]
