Use of .gitignore opt-in strategy

[halcwb]

I couldn't help noticing that you had some commits like d60b244.

That's why I always start with * in my .gitignore and then explicitly add all that is required for a reproducible build.

Like:

# Use an opt-in strategy
*

# Add .gitignore and .gitattributes
!.gitignore
!.gitattributes
!.dockerignore

# Add license
!LICENSE.txt
!LICENSE

# Add todo list
!ToDo.txt

# Add md files
!*.md

Just a tip :-)
