I have added my GitHub account in SourceTree. Good so far.
On GitHub, I created a new repository. If I now click the '+' to add a new tab in SourceTree, select Remote, I can see the repository I just created in GitHub. Still doing good.
If I now add code to the local folder for this project, it shows up as changed files in SourceTree. I stage them all and commit them. Still doing good.
This operation completes without error but when I look on the GitHub website, I don't see any code.
What am I doing wrong?
