I found a discussion thread with an example in the P5js web editor that runs in the web editor but not when I tried copying to the desktop editor. I’m relatively new to P5js and clueless as to why it won’t run on the desktop, unless it relies on a library that I don’t have.

Hello,
These are in the _index.html_ of the P5.js:
```auto
```
You must add them to the _index.html_ of your Processing p5.js editor.
And voila!
Sometimes you need a web server as well.
I use this one:
_[Web Server for Chrome - Chrome Web Store](https://chrome.google.com/webstore/detail/web-server-for-chrome/ofhbbkphhbklhfoeikjpcbhemlocgigb/)_
Getting started:
_[get started | p5.js](https://p5js.org/get-started/)_
