How to Synch Git Hub with Azure?

Question

Hi,

I have a Static Web App that is hosted on Azure, with the code residing on GitHub.

If I update the code on GitHub, what is the process to inform Azure of code updates?

I understand there is a way to synch the two of them?

Can you explain:

1. How on a one time basis- trigger Azure to re-read the code from GitHib
2. Synch code updates from GitHub to Azure.

Thanks so much!

Dan
