 ## I want to contribute!
 
-That is great! Just fork the project in github. Create a topic branch, write some code, and add some tests for your new code.
+That is great!
 
-To run the tests:
-
-- Use the latest redis master branch.
-
-- Run ```make test```. This will run 2 instances of redis. We use 2 redis
-	servers, one on default port (6379) and the other one on (6380). Both have
-	authentication enabled with default password (foobared). This way we can
-	test both sharding and auth command. For the Sentinel tests to we use a
-	default Sentinel configuration that is configured to properly authenticate
-	using the same password with a master called mymaster running on 6379.
+Please see CONTRIBUTING.md on project's root directory for follow up how to contribute to Jedis project.
