So a tree describes a directory structure at a specific point in time.
|
|
|
|
It would be nice if we could remember when that state existed, and who authored it, right?
|
|
|
|
Enter: commits. They are objects that point to a tree and contain some additional metadata. You can create a commit using
|
|
|
|
git commit-tree <tree> -m "Description of your commit"
|
|
|
|
Make a commit from the tree in this repository!

git add .
|

git write-tree

git update-index --remove empty_file
