How to load the footprints in Altium

Hi Jeremy! Thanks for your question. The instructions are available in the FAQ. One place many people stumble is that you need to click "Next" on the first screen after selecting the PCAD import. It's on the screen following the first one that you select the file downloaded from SnapEDA. Good luck, and let me know if you have any other issues!

Instructions to import into Altium

Select File > Import Wizard.
Select PCAD library from the list and click Next.
Click Next again to skip importing a design.
The next dialog will be to import a PCAD library. Add the file downloaded from SnapEDA and follow the rest of the prompts.

Here's a video to show the process: https://youtu.be/jM6L8SiklaQ
