title: GitHub - Green lines next to text?
body: <p>This is my first GitHub, I want to write a report but this green line keeps popping up next to my text and I don't want it to do so. This is what my text should be but it appears like this: <a href="https://gyazo.com/f593db78a387623fcad31c744ac9a120" rel="nofollow noreferrer">https://gyazo.com/f593db78a387623fcad31c744ac9a120</a></p>
  
  <p>How can I control this?</p>
  
  <h1>System Hardware Final Report</h1>
  
  <p>The project designed shows the functioning behind computer's.</p>
  
  <p>The topics covered will include:</p>
  
  <ul>
  <li>Introduction to Binary &amp; Logic Gates
  
  <ul>
  <li>Commonly Used Parts</li>
  <li>Logic Functions</li>
  </ul></li>
  <li>The Timing Signal Generator</li>
  <li>The Bus, Arithmetic Unit and Program Counter</li>
  <li>Data Registers and the Memory Address Register</li>
  <li>Program Memory</li>
  <li>The Control Signal Generator</li>
  </ul>
  
  <p>The outcome of this project will enable one to build a computer with a CPU (central processing unit) that can do simple
  instructions such as moving data from one register to another and performing simple arithmetics.</p>
  
  <h2>Introduction to Binary &amp; Logic Gates</h2>
  
  <h3>Breadboard</h3>
  
  <p>The breadboard will be used to setup the components and all circuits. It is divides in 8 parallel coloumns and contains 5 columns that
     provides power. In fact, the breadboard is made up of two important supply connections: the <code>VCC</code> for the red
     line and the <code>GND</code> for the blue line. The holes are all connected row-by-row in lines of 5.</p>
