# Add Mary Instructions
## Overview
You can tell Mary how you want to process your tokens. Mary will read “Mary instructions” and try to follow them.
There are some use cases:
* Append UTM parameters in every link
* Remove “https\://” or specific text in the brief doc.
* Validate specific token values
# Add document-level instructions
For example, add “Mary instructions” sections like this example.
# Add token-level instructions
You can add Mary instruction on the token level like this as well.
*Note: Marketo does not support emojis.*
