The update process for Raneto is as follows:

• Make a backup of your content folder and your config.js. Copy these files somewhere else
• If you have edited the template you may also need to backup the views folder and anything you have edited in the public folder
• Download the latest version of Raneto from the releases page
• Extract the Raneto zip/tar.gz and overwrite all of the files in your existing Raneto install, replacing all files and folders
• Copy your content folder and config.js file from your backup location back into the install location
• If you have edited the template then copy your custom views and public files back as well
• Run npm update from the root of your install
• Restart node (npm start) and you should be running the new version of Raneto
