 ## Adding the package as a dependency
 
-Currently, this library is deployed to Github Packages, so you need to configure your maven repositories accordingly.
+Currently, this library is published to Maven Central, but is released for Neo4j internal use cases and should not be
+considered as a supported product.

 ## Development & Contributions
 
-### Internal Maven Repository
-
-For the build to succeed, it needs the package [build-resources](https://github.com/neo4j/connectors-build-resources)
-that is being published to Github Packages.
-In order to access it, create a personal access token in Github and give it a permission to read packages.
-Then add the following content into `settings/servers` inside ~/.m2/settings.xml.
