 Currently only simple quering using raw Cypher queries is implemented, but there are few items on the Roadmap.
 
-### Bolt_sips
+## Existing libraries
 
-One may say "there is already a library for communication with Neo4j". They are right **BUT** first and foremost, `bolt_sips` is left unmaintained ([discussion](https://github.com/florinpatrascu/bolt_sips/issues/109)). There were few attempts to continue that, but there is still no library that would take advantage of Elixir structs, protocols and behaviours to provide robust extensibility. Secondly, `bolt_sips` is just a driver. This library purpose will be to provide complete user experience when interacting with the DB. 
+There were already few attempts to write a driver for Bolt protocol but all of them seem to be clumsy in terms of protocol logic - many things are "hardcoded" as in the docs instead of being thought out for the server's operation and coding a reusable solution. They are not taking advantage of Elixir structs, protocols and behaviours to provide robust extensibility.  
+Secondly, those libs are just a driver and this library purpose is to provide complete user experience when interacting with the DB.  
 This should be solved by building Ecto-like support for the Cypher query language.  
 
+At this point, it's worth noting that this library may not be faster than `bolt_sips` or `boltx` due to greater usage of Protocols and structs.  
+You can modify tasks from `example_app` to benchmark those on your data.
+
 ## Installation
 
 The package can be installed by adding `neo4ex` to your list of dependencies in `mix.exs`:
