# Update Theme
Before installing a new version of this theme please do not forget to make a backup of the version you are currently using.
If you have not modified any files in the theme folder previously, you can simply upload the new file
weiss-pro.zip in the Ghost Admin and that's it.
However, if you have made changes to some files previously, you must apply those changes to the files in the folder corresponding to the latest version, otherwise your changes will be overwritten.
If you want to make small changes to the theme (e.g. styles), it is best to make them directly in the Ghost Admin so they can be persisted.
