 ABC is a command-line too to interact with appbase.io. 
 It can also serve as a swiss army knife to import data from any popular data source (Postgres, SQL, Mongo) to ElasticSearch. 
 This feature works with minimum configuration and is totally automatic. 
-In certain sources like Postgres and Mongo, you can even tail the database and keep ElasticSearch cluster in sync with the data in the source.
+In certain sources like Postgres and Mongo, you can even keep the database and ElasticSearch cluster in sync such that any change from source gets added in destination as well.

+## 2. Key Benefits
+
+ABC comes with a lots of benefits over any other traditional solution to the same problem. Some of the key points are as follows -
+
+- Whether your data resides in Postgres or a JSON file or MongoDB or in all three places, abc can index the data into Elasticsearch. Besides these, it also supports CSV, MySQL, SQLServer, and Elasticsearch itself to an Elasticsearch index.
+- It can keep the Elasticsearch index synced in realtime with the data source. (Note: Currently only supported for MongoDB and Postgres)
+- `abc import` is a single line CLI command that allows doing all of the above. It doesn’t require any external dependencies, takes zero lines of code configuration, and runs as an isolated process with a minimal resource footprint.
+- abc also supports configureable user defined transformations for advanced uses to map data types, columns or transform the data itself before it gets indexed into Elasticsearch.

 ABC allows the user to configure a number of data adaptors as sources or sinks. These can be databases, files or other resources. Data is read from the sources, converted into a message format, and then send down to the sink where the message is converted into a writable format for its destination. The user can also create data transformations in JavaScript which can sit between the source and sink and manipulate or filter the message flow.
