# Particle Web IDE

For this tutorial we will be writing the application code that we will flash our Argon with in the Particle Web IDE. 

So start by going to build.particle.io/build/new and sign in to your Particle account if you have not already. You can also get to the web IDE through the Particle Console.

Start by giving the new app a name. For example I called Blynk\_Relay\_Tutorial.
