Hi!

I just release Pylon v2. Due to some breaking changes I need to adapt
the docs.

 ## Setup new Pylon service
 
-### Setup Pylon
+Pylon allows you to create a new service using the `npm create pylon` command. This command creates a new Pylon project with a basic project structure and configuration.
+During the setup process, you can choose your preferred runtime, such as Bun, Node.js, or Cloudflare Workers.

 ### Creating a new project
 
 To create a new Pylon project, run the following command:
 
 ```bash
-pylon new my-pylon-project
+npm create pylon my-pylon@latest
 ```
 
-This will create a new directory called `my-pylon-project` with a basic Pylon project structure.
