# Rules
Rules allow you to create reusable instructions that guide how CodeMate Work responds to your requests. They can be used to apply project-specific requirements, team guidelines, or preferred ways of working consistently across conversations.
For example, you can create a rulebook that instructs Work to follow specific coding conventions, use a particular response format, or follow project guidelines.
### Creating a Rule
**1. Open Rules**
Open the Rules section in the CodeMate Work interface.
**2. Create a new Rulebook**
Click + New and select Create new rule.
**3. Add Rulebook details**
Enter a name for the rulebook and provide the instructions you want Work to follow.
**4. Save the rulebook**
Save the rulebook to add it to your available rulebooks.
### Applying a Rule
Once a rulebook has been created, you can apply it to a Work conversation when you want its instructions to guide the response.
**1. Mention the Rule**
In the conversation input, type @ to open the available rules.
**2. Select a Rule**
Choose the rulebook you want to apply to the conversation.
**3. Send your request**
Enter your request and submit it. Work will use the selected rulebook's instructions while processing the request.
### Managing Rules
The Rules section provides a centralized view of your rulebooks. You can review existing rulebooks, edit their instructions, enable or disable them, or delete rulebooks that are no longer needed.
