# Import

Users also have the option to add Code System by importing content. 

The import functionality can be accessed from the Resources page by pressing the ![](https://content.gitbook.com/content/ckoNppM37m1A9KBre9xY/blobs/1iKKyFYX9mwZsdsv0yCu/import_button.png)button located in the header area.
