**Use case :** Imagine we have just created a project with `composer create-project awesone-project` (currently **V0.2**).
2 weeks later, there is a new release (**V0.3**). How to update your project ? 
Since `composer update` only updates the project dependencies, it is not what we are looking for.
Composer doesn't know about awesome-project since it's not in our **composer.json**.

After trying many git solutions, I've come to this : 

`git archive --output=changes.zip HEAD $(git diff --name-only SHA1 SHA2 --diff-filter=ACMRTUXB)`

This command will check for changes between the two commits and ignore deleted files.
And after checking, it will copy those files into an archive.
So you must `git clone awesome-project` before doing this.

`git diff --name-status SHA1 SHA2 | grep "D\t"`

This one will show you deleted files between the 2 commits, to help applying changes to your project.

After deleting files, you can unzip *changes.zip* and run `\cp -rf ../changes/* .` from your project directory to update your project with modified files.

**PS :** Some files could not be present in the latest commit. So you can first run `git checkout SHA1` before running theses commands.

Nope : `git am --abort`

* Git pull from remote origin and merge

```
git remote add awesome-project https://github.com/awesome/project.git
git remote update
git tag -l
git checkout tags/v4.1.0 new-branch
git branch -f master new-branch
git checkout master
Switched to branch 'master'
Your branch and 'origin/master' have diverged,
and have 1298 and 3 different commits each, respectively.
  (use "git pull" to merge the remote branch into yours)
```
I've just added 1300 commits to my git history ... Nope
```
git branch -D new-branch
git reset --hard origin/master
git remote rm awesome-project
git remote update
```
