title: What does information between "@@" means in git dif
body: <p>When I use git diff command in git I see output like this:</p>
  
  <p>@@ -35,14 +41,12 @@</p>
  
  <p>and can't realize what does it mean. I guess that minus means a row when deletion was made, and + is row with insertion. Am I right?</p>
