Before you start!

The first step is to install Profound.js onto your local machine by using 'npm install profoundjs'. Click

for more detailed installation instructions.

Please note...

You can and are welcome to use any Node.js debugger you prefer with Profound.js; however, this walk-through illustrates using VS Code, as it is one of the more popular, free, and easy to use debuggers for Node.
