title: Add git repository to github subdirectory
body: <p>I have a directory <code>lessons</code>, then under it subdirectories <code>20200110</code>, <code>20200111</code>, <code>20200112</code> etc. Each of the subdirectories contain lesson files. I want this directory structure on my github site just like it is on my computer. How can I do this? When I do <code>git init</code> inside, say, <code>20200110</code>, add, commit, etc., the next step is to do <code>git remote add origin remote repository URL</code>, however, I can't figure out what that remote repository URL is supposed to be. What am I missing? Again, I need to do this for each day's lessons.</p>
