I am just trying to do the most basic stuff - create two linked pages.
I followed instructions from here: https://docs.github.com/en/github/working-with-github-pages/adding-content-to-your-github-pages-site-using-jekyll
My site is at github.com/adhodgson/Releases.
My index.md file shows up fine, but when I browse to …Releases/Instruct I get a 404 error. However, the file at …Releases/Test.html shows up fine.
What are I doing wrong?
