README isn't displaying

I’m looking at setting up my very first repository in GitLab. It literally has one file: However, the read me isn’t visible on the project page. If I click on the file, I can’t even preview it (it just lets me download it).

Is there something very simple that I’m missing? The file itself only has this text:

# Test

Of course, a few minutes later I figure out the problem. The file I originally created via PowerShell by redirecting an echo statement to a file seemed to cause the issue.
