build problem - no such file or directory

Using Win11, following your docker tutorial (and file structure&naming), I used the following two commands to build:
docker build -t insta360-auto-converter . here I had to move the Dockerfile one folder up or use this:
docker build . -f insta360-auto-converter/Dockerfile -t insta360-auto-converter
