I’ve heard many people talk about building in public at the start to get potential users interested, but i’m not a tech guy and I dont know what sort of content to post to ‘build in public’. Should it be content that my staff (developers) are working on?

And I feel a little awkward reaching out to friends that I have not contacted in awhile, who do you guys usually contact to get beta testers for your startup?

For context: I’m building an app that helps beginners learn how to code
