I am new to developing for Salesforce. I have installed the Salesforce Extension Pack for Visual Studio Code. So far I have been able to create a project, authorize an org and deploy a single Apex class to a Salesforce Trailhead org.
Where I'm stuck is being able to deploy the entire package to my Salesforce org instead of just a single class. I followed the Trailhead Visual Studio Code training but it ends at deploying just a single Apex class. I've search but can't find anything that answers my question.
