Git - How to resolve conflicts in Git

■ Check a status of conflicts in Git.
$ git status

On branch master
Your branch and 'origin/master' have diverged,
and have 7 and 2 different commits each, respectively.
  (use "git pull" to merge the remote branch into yours)

You have unmerged paths.
  (fix conflicts and run "git commit")

Unmerged paths:
  (use "git add <file>..." to mark resolution)

 both added:      .project

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

 modified:   .gitignore
 modified:   build.gradle

■ Edit a conflict file
 ○Before (conflicted code in a file)

<<<<<<< HEAD
sample_head
=======
sample_master
>>>>>>> master

 ○After (resolved code in a file)

<<<<<<< HEAD
sample_master
>>>>>>> master

■ Commit (You can resolve this by adding the file fixed)
$ git add .project
$ git commit

■ Check if it was fixed
$ git show | head
