GitHub actions–Run vs Use

I recently added a Github Actions workflow to my Extensions.Caching.PostgreSQL open-source project.

Here is the workflow I’m using:

Something that I found confusing when using GitHub actions was that for some steps you had to use the uses syntax, while others use the run syntax.

Let’s investigate the difference between the two.

Uses

uses is used for actions that run as part of a step in your workflow.

Some actions require inputs that must set with the with keyword:
