Contributing by adding absent links?

Hello! I truly love this corner of the internet and, although I am entirely amateur as far as etymology credentialing, I would love to contribute to it being as good as it can possibly be, namely, by adding links to entries when they are referenced. I looked around and didn’t see guidelines on this — is this something that I could do, and if so, how?

Again, truly appreciate all of the work put into this project.
