First steps with particle

Hi all,
i’m new here and is the first time with an IOT device, so i want to learn and i’ve bought the air quality kit sensor (WI-FI), i’ve already installed the device and connected to the particle app mobile.
Now i need help with the code, i have the particle workbench on visual studio and i’ve already downloaded the github repository and i try to import the “project.properties” in particle workbench, but thrown an error:
Could not find library: Grove_Air_quality_Sensor@1.0.1
Error: Could not find library: Grove_Air_quality_Sensor@1.0.1

at c:\Users\andre.vscode\extensions\particle.particle-vscode-core-1.11.1\src\cli\index.js:93:66
at async Promise.all (index 2)

How can i fix them? There is a “guide” for a newbie?

Thanks!

Up pls!
