Adding a glossary at the end of tutorials

Which area of the website does this enhancement relate to?

Processing's text tutorials

Describe the enhancement

At the end of the tutorials on the Processing website, there could be a glossary at the end with key words of the tutorial and definitions for easy reference.

Why is this enhancement important?

When I was looking through them, I noticed there was lots of jargon scattered throughout the tutorials and not all of them were clearly defined (or were in a different linked page). For beginners, this might get confusing and they might spend a while going back and reading through the tutorial to figure out what words mean, so I thought a
glossary section would help.

The current format has some words linked to a different page. While this is useful, it can be inconvenient since it involves extra navigation of pages (and can get disorganized if the user opens them in another tab). This would keep key terms in a centralized, consistent location for each tutorial for quick referencing, which is especially in scenarios where a user has to go back to a previous tutorial to refresh their memory.
