# Blueprints

> A blueprint is a pre-defined set of rules and cart item filters you can add from the Rule Builder. You can also create your own blueprints from a campaign's rules or cart item filters and reuse them across multiple campaigns in the same Application.

> For the complete documentation index, see [llms.txt](https://docs.talon.one/llms.txt).

:::note[Blueprints vs campaign templates]
Blueprints are similar to [campaign
templates](/docs/product/campaigns/templates/overview.md) but serve different purposes:
- Campaign templates define the entire campaign structure including budgets, rules, and
  potential placeholders.
- Blueprints are reusable rules and cart item filters.
  They can be added to a campaign without altering its overall structure.

## Add a blueprint to a campaign

To add the content of a blueprint to your campaign:

1. Open your campaign and select <RuleBuilder className="icon"/> **Rule Builder**.
1. In the top-right corner of the Rule Builder, click  <BlueprintIcon className="icon"/> **Blueprints**.
1. Browse the list of available blueprints that appears, or use the search bar
   to find a specific blueprint.
1. Click the blueprint you want to add.

:::important
The rules added to your campaign from a blueprint exist independently.
Changes you make to the rules within your campaign do not affect the original blueprint.
:::

## Find a blueprint

In <RuleBuilder className="icon"/>
**Rule Builder** > <BlueprintIcon className="icon"/> **Blueprints**,
use the search bar at the top of the list to find blueprints by name or
description. You can also filter by category to find the
right blueprint for your campaign requirements.

To filter the results, use the following categories:
- **Promotions:** Rules for generating discounts.
- **Pricing:** Rules for managing item pricing.
- **Loyalty:** Rules for managing loyalty programs.
- **Custom:** Extra filter you can use when saving your own blueprints.

To display only the blueprints created in the current Application, toggle
**Created in this Application**.

## Create a blueprint

You can save rules or cart item filters from your campaign as blueprints. By default, the
blueprint contains all the rules and cart item filters present in the campaign. After you
create a blueprint, it becomes available in all the campaigns of the current Application.

To create a blueprint:
1. In the <RuleBuilder className="icon"/> **Rule Builder**, locate the rule you want to
   create a blueprint from.
1. At the top right of the rule, click <Save className="icon"/> **Create Blueprint**.
1. Configure the details:
   - **Name:** Enter a name for the blueprint.
   - **Category:** Select a category from the dropdown, for example, **Custom**.
   - **Description:** (Optional) Add a description.
   By default, the blueprint contains all the rules that are part of the current campaign.
1. (Optional) In the **Rules** section, delete any rules you want to exclude from
   the blueprint. You can also rename the rules.
1. Click **Create Blueprint**.

## Delete a blueprint

Deleting a blueprint permanently removes it from the list of available blueprints. This
does not affect any campaigns that use the blueprint.

To delete a blueprint:

1. Open your campaign and select <RuleBuilder className="icon"/> **Rule Builder**.
1. In the top-right corner of the Rule Builder,
   click  <BlueprintIcon className="icon"/> **Blueprints**.
1. Browse the list of available blueprints that appears, or use the search bar to find a
   specific blueprint.
1. On the blueprint you want to delete, click <Trash className="icon"/> **Delete**.
1. In the pop-up that appears, click **Delete Blueprint**.
