# Guidelines / Heuristics

Heurio offers a comprehensive set of guidelines that can be referenced when creating heurios on website elements. This guide provides an overview of how to incorporate these guidelines and utilize them effectively in the feedback process.

## Setting a global guideline

1. For each project, users can set a global guideline, providing a default guideline for each heurio created within that project.
2. This option ensures consistency across the project's evaluations.

## Locking a rule (heuristic)

1. In the Chrome Extension, users can lock a guideline's rule by clicking on the "Book of Guidelines" button in the bottom right corner.
2. Select the guideline you need and then click on the rule you wish to lock.
3. This option is useful for evaluating a website by each rule of a guideline, allowing for a comprehensive, rule-by-rule review.
4. **The locked rule will be selected by default** for each new heurio in order the make your review more productive.
