How to Create a Robots.txt File

So, here's the contents of my robot.txt file: (If you don't mind, could you quickly peruse my site and advise where I MIGHT need a disallow stmt?

User-agent: *

allow: /

I've just learned that I also need to insert the URL with the link to my sitemap. So, would that look like this?

User-agent: *

allow: /

https://myproaudiogear.com/sitemap.txt

Do I have to use an XML ext? If so, how do I do that within the txt file?
You guys REALLY REALLY should have SOME kind of tutorials on this stuff!! Honestly, HTH do you expect total noobies to just pull this stuff out of thin air?

Hi George,

We do not create robots.txt file and do not provide any instructions. You can find some tutorials over the internet like this one:

I think you might be missing the point on this one.
IF someone is using your App (like I am, and the person above), to generate the entire site in HTML....
No one wants to Manually re-create the robots.txt file each time they do an export.
Its too easy to skip and miss the step.

So, what we're looking for, is the ability to add one or more "include files" in the HTML export.
And robots.txt would be a text file that we define what its contents are...
And when we export the site to a folder, the robots.txt file we defined, would be exported there.

Fairly simple request.
And it'd save your users a ton of headaches.
