Git Pull from GitHub

When working as a team on a project, it is important that everyone stays up to date.
Any time you start working on a project, you should get the most recent 
changes to your local copy.
With Git, you can do that with pull.
pull is a combination of 2 different commands:
fetch
merge
Let's take a closer look into how fetch, merge, and pull works.
 fetch gets all the change history of a tracked branch/repo.
So, on your local Git, fetch updates to see what has changed on GitHub:
git fetch origin
remote: Enumerating objects: 5, done.
remote: Counting objects: 100% (5/5), done.
remote: Compressing objects: 100% (3/3), done.
remote: Total 3 (delta 2), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (3/3), 733 bytes | 3.00 KiB/s, done.

   e0b6038..d29d69f  master     -> origin/master
Now that we have the recent changes, we can check our 
status:
git status
On branch master
Your branch is behind 'origin/master' by 1 commit, and can be fast-forwarded.
  (use "git pull" to update your local branch)

nothing to commit, working tree clean
We are behind the origin/master by 1 
commit. That should be the updated 
README.md, but lets double check by viewing the 
log:
git log origin/master
commit d29d69ffe2ee9e6df6fa0d313bb0592b50f3b853 (origin/master)

    Updated README.md with a line about GitHub

    merged with hello-world-images after fixing conflicts

That looks as expected, but we can also verify by showing the differences 
between our local master and 
origin/master:
git diff origin/master
diff --git a/README.md b/README.md
index 23a0122..a980c39 100644

 Hello World repository for Git tutorial

That looks precisely as expected! Now we can safely merge.
 merge combines the current branch, with a specified branch.
We have confirmed that the updates are as expected, and we can merge our current branch (master) with 
origin/master:
git merge origin/master

Check our status again to confirm we are up to date:
git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean
There! Your local git is up to date!
But what if you just want to update your local repository, without going through 
all those steps?
pull is a combination of fetch and merge. It is used to pull all changes from 
a remote repository into the branch you are working on.
Make another change to the Readme.md file on GitHub.
Use pull to update our local Git:
git pull origin
remote: Enumerating objects: 5, done.
remote: Counting objects: 100% (5/5), done.
remote: Compressing objects: 100% (3/3), done.
remote: Total 3 (delta 1), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (3/3), 794 bytes | 1024 bytes/s, done.

That is how you keep your local Git up to date from a remote repository. In the next chapter, we will look closer at how
push works on GitHub.
