* Tree - Grouping blobs together
* Commit - A specific state of a tree with more meta information (e.g. author/date/message)

### Structure of .git file

* HEAD
* objects/info/packs
* description
* config
* COMMIT\_EDITMSG
* index               //contains all file name  in a repository. to list this first **`git init`**  then **`git ls-files --stage`**
* packed-refs
* refs/heads/master
* refs/remotes/origin/HEAD
* refs/stash
* logs/HEAD
* logs/refs/heads/master
* logs/refs/remotes/origin/HEAD
* info/refs
* info/exclude
