Download your theme files from the course portal. 

You'll find the Divi Child Theme zip file in your portal dashboard under "Download Your Theme ."

The zip file consists of:

• Your theme -- Do not unzip this file. WordPress installs themes directly from the zip, so it needs to stay compressed. 
• Theme Builder Files (this includes your preset, variable and theme builder file for your header/footer and blog post, search, and 404 page and your global variable files.) 
• Lay out Pack (consists of all page layouts and the global preset style guide) 

Save it somewhere easy to find — your desktop is fine.
