# My Feeds > Parameters > Profiles - Feed.biz

[Rules](https://doc.common-services.com/en/article/my-feeds-parameters-rules-feedbiz-prestashop-c9ytus/) don't work by themselves. Instead, you group your rules together inside a Profile, which you then apply to a Category. This makes it easy to apply a whole set of rules to your product categories all at once.

### Step 1: Create and Name a Profile

To start grouping your rules, you need to establish a profile:

1. Click the **+ Add a Profile** button at the top left of the configuration screen.
2. In the **Profile name** field, type a clear, recognizable name

### Step 2: Set a Default Profile (Optional)

* **Default Profile Checkbox:** When you check this box (as shown in **below image**), this profile becomes your store's default option. 
* **Why use it?** If you forget to assign a specific profile to a product category later on, Feed.biz will automatically apply this default profile's rules to those categories during the PrestaShop import phase. 
* If you want a profile to apply only to specific, hand-picked categories, leave this box unchecked.

### Step 3: Assign Rules

Once your profile is named, you can assign your pre-defined rules to it:

1. Click the **+ Add Rule Item/s** button on the right side of the panel.
2. A new dropdown row will appear. Click the dropdown menu to see all the rules you have previously built.
3. Select the rule you want to include in this profile.
4. **Manage your rules:**
* **Add multiple rules:** Click **+ Add Rule Item/s** again to stack multiple conditions inside a single profile.
* **Remove a rule:** Click the red minus (**-**) icon next to any rule row to detach it from the profile.
* **Delete the profile:** If you want to wipe out the profile completely, click the red **Remove this Profile** link at the top left.

### Step 4: Save Your Work

Once you have finished linking your rules into the profile, click **Save** to store your configuration, or click **Save & continue** to finalize the profile and move to the next stage of your setup.

> **What's Next?** Now that your profile contains its import rules, head over to the **Categories** parameters page to map this profile directly to your shop's product categories.
