The update procedure for your CMS depends upon the method you used to install Netlify CMS.
## Package Manager
If you are using a package manager like Yarn or NPM, you will use their standard procedure to update. This is how both the Hugo and Gatsby starters are set up.
## CDN
If you are using the CMS through a CDN like Unpkg, then that depends on the version tag you are using. You can find the version tag you are using in the `/admin/index.html` file of your site.
