You must edit all merge conflicts and then mark them as resolved using git add code example

Example: Automatic merge failed; fix conflicts and then commit the result.

# Step 1:  
# Navigate into the local Git repository that has the merge conflict.

cd REPOSITORY-NAME

# Step 2: 
# Generate a list of the files affected by the merge conflict. 
# In this example, the file styleguide.md has a merge conflict.

git status

> # On branch branch-b
> # You have unmerged paths.
> #   (fix conflicts and run "git commit")
> #
> # Unmerged paths:
> #   (use "git add ..." to mark resolution)
> #
> # both modified:      styleguide.md
> #
> no changes added to commit (use "git add" and/or "git commit -a")

# Step 3: 
# Open your favorite text editor, such as Atom, and 
# navigate to the file that has merge conflicts.
# To see the beginning of the merge conflict in your file, 
# search the file for the conflict marker <<<<<<<. 
# When you open the file in your text editor, 
# you'll see the changes from the HEAD or base branch 
# after the line <<<<<<< HEAD. Next, you'll see =======, 
# which divides your changes from the changes in the other branch, 
# followed by >>>>>>> BRANCH-NAME. 
# In this example, one person wrote "open an issue" in the base or HEAD 
# branch and another person wrote "ask your question in IRC" in the 
# compare branch or branch-a.

If you have questions, please
<<<<<<< HEAD
open an issue
=======
ask your question in IRC.
>>>>>>> branch-a

# Step 4:
# Decide if you want to keep only your branch's changes, 
# keep only the other branch's changes, or make a brand new change, 
# which may incorporate changes from both branches. 
# Delete the conflict markers <<<<<<<, =======, >>>>>>> and 
# make the changes you want in the final merge. 

# In this example, both changes are incorporated into the final merge:

If you have questions, please open an issue or 
ask in our IRC channel if it's more urgent.

# Step 5:
# Add or stage your changes.

git add .

# Step 6:
# Commit your changes with a comment.

git commit -m "Resolved merge conflict by incorporating both suggestions."
