How can I give credit to originals in hive?

It's really easy. With markup language, you can format your texts easily.

Use the quote tag > like this:

> This is a quoted text.

It'll become:

This is a quoted text.

Then mention where it's quoted from, or you can link to the original text by adding the link into the quote:

> [A famous Shakespeare quote here.](https://en.wikiquote.org/wiki/William_Shakespeare)

Which will become:

A famous Shakespeare quote here.
