Do not ignore the gitignore but use git/info/exclude instead

Do a research and maybe adapt

As discussed, I'd rather add a hint about the global excludesfile

[core]
    excludesfile = ~/.gitignore

I think I would still prefer a hint about this section from the Atlassian Tutorials

Personal Git ignore rules
You can also define personal ignore patterns for a particular repository in a special file at .git/info/exclude. These are not versioned, and not distributed with your repository, so it's an appropriate place to include patterns that will likely only benefit you. For example if you have a custom logging setup, or special development tools that produce files in your repository's working directory, you could consider adding them to .git/info/exclude to prevent them from being accidentally committed to your repository.

From what I understand from this tutorial page, the default excludefile setting is the .gitignore in the root, and only really useful when you want to set more. But this is discouraged?
