 This repository contains the source code for the Keycloak Node.js adapter. This module makes it simple to implement a Node.js Connect-friendly
 application that uses Keycloak for its authentication and authorization needs. 
 
+## Supported Node.js versions

+The Keycloak Node.js adapter strives to be compatible with the versions that are [actively supported](https://github.com/nodejs/release#release-schedule) by the Node.js project. Support for versions of Node.js that are [considered end-of-life](https://github.com/nodejs/release?tab=readme-ov-file#end-of-life-releases) can be dropped in future releases, and will not be considered a breaking change that requires a major version bump.
