title: How do I know which command serverless uses to build?
body: <p>I have a nodejs application and use <code>serverless</code> to manage AWS infra for lambda and API Gateway. I use the command <code>serverless deploy</code> to deploy to AWS. There is a <code>.serverless</code> folder created by this command which includes a zip file of my code and <code>node_modules</code>. I was wondering which command <code>serverless</code> uses to build the code and install the dependencies. Can I change the command it uses?</p>
