 ## Prerequisites
 The application requires ElasticSearch as its output.
 
 1. ElasticSearch (version 5+/6+) should not require any additional configuration or installation, just download and run from [Elastic](https://www.elastic.co/products). 
 
-2. Download the latest release of excelastic-1.2.6.jar and the configuration.json (optional) file from [GitHub releases](https://github.com/codingchili/parser-excel-elasticsearch/releases).
+2. Grab the latest .jar file from [releases](https://github.com/codingchili/parser-excel-elasticsearch/releases).

 ## Running

 Running the application, filename and index is required, to import from the terminal run:
 ```
-java -Xmx1g -jar excelastic-1.2.6.jar <filename> <index> <mapping> --clear
+java -Xmx2g -jar excelastic-1.2.7.jar <fileName> <indexName> --mapping mappingName --clear
 ```
 If running with --clear, then the existing index will be cleared before the import starts.
 
 To run with the web interface, run the following in your terminal:
 ```
-java -Xmx1g -jar excelastic-1.2.6.jar
+java -Xmx2g -jar excelastic-1.2.7.jar
