Some hints how to use GIT for your code







Commit often.
Use appropriate commit messages.
Do not rename the file names manually (use git mv)
New files are not automatically indexed, must be added.
Careful with git add .
Rather choose the files: git add file1
Write a .gitignore file or use git ignore for files that
you never want to commit (e.g. big datasets)
