Can someone walk me through setting up my vscode extension for netsuite?

Click on Extensions and then search for "SuiteCloud Extension for Visual Studio Code". Once you have that installed, you can open up your SuiteCloud project folder. You should have options on your command palette (View > Command Palette) for SuiteCloud now. The first thing you'll need to do is Setup Account where it creates an access key for your client to access your NetSuite accounts. You'll need to set up a separate access key for each account you want to connect to.
