title: How does sequelize.sync() work, specifically the force option?
body: <p>What does the force option on sequelize.sync() do?</p>
  
  <pre><code>sequelize.sync({
      force: true
  });
  </code></pre>
  
  <p>Specifically, I am interested in knowing what force: false does? Will it not sync the schema with the database?</p>
  
  <p>Are there any formal docs for sequelize? I could only find examples inside the docs.</p>
