The document discusses best practices for developing and deploying code outside of a WordPress repository directory. It recommends using version control like Git and GitHub, semantic versioning, and developing locally before pushing commits and tagging releases. For deployment, it describes options like FTP/SFTP, using an updater library directly in projects, or an updater plugin. Continuous integration is also presented as an option to automatically update code on every push through webhooks. The document provides examples and demos of these techniques.
