title: Add/remove custom stop words with spacy
body: <p>What is the best way to add/remove stop words with spacy? I am using <a href="https://spacy.io/docs/api/token" rel="noreferrer"><code>token.is_stop</code></a> function and would like to make some custom changes to the set. I was looking at the documentation but could not find anything regarding of stop words. Thanks!</p>
