The Node.js website offers three types of documentation: API reference, ES6 features, and Guides. The API reference provides detailed information about built-in modules, ES6 section describes features, and the Guides have long-form articles. Node.js is open-source with three types of releases: Current, LTS, and Nightly available for download. Verification of binaries can be done with SHA checksums. The latest directory is for the latest Current release, while the latest-codename directory is for the latest LTS release, both found on the website.
