title: How to use PyCharm to debug Scrapy projects
body: <p>I am working on Scrapy 0.20 with Python 2.7. I found PyCharm has a good Python debugger. I want to test my Scrapy spiders using it. Anyone knows how to do that please?</p>
  <h3> What I have tried</h3>
  Actually I tried to run the spider as a script. As a result, I built that script. Then, I tried to add my Scrapy project to PyCharm as a model like this:
  <pre><code>File-&gt;Setting-&gt;Project structure-&gt;Add content root.
  </code></pre>
  <p>But I don't know what else I have to do</p>
