Git 101: How to Handle Merge Conflicts

In the last post, I talked about how to create a Git repository and upload it to GitHub. In this post, I’m going to talk about how to resolve Git conflicts.

Setting Up Our Environment

First, we’re going to create a Git Repository for the user Doug. Since I already covered that in the last post, I’m bring to breeze through those steps below:
