In this final episode of the “Get started with Mergado” series, learn how to **make bulk edits** of your XML feed with Mergado or how to **activate apps** in [Mergado Store](https://store.mergado.com/).
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/getstartedwithmergadovol31.png)
In Mergado, rules allow **applying bulk changes to products**. They can be applied either to **all products** in your feed, or to a saved **query of products**. This allows you to first filter those products that you wish to edit, then create a rule and apply it to that product query.
## How to create a rule
Rules can be created on the **Rules** page by clicking *Create rule* on the top right (image 15).
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/create-a-rule.png)
On the **New rule** page (image 16), first **name** your new rule (step 1), **choose a query** which you want the rule to be applied to (step 2), **choose a** desired **rule type** (step 3), **choose** which **element** (attribute) will be changed by the rule (step 4), and **enter a new value** for that element (step 5). The value can be either a **static text** (i.e. the given element in all products of the selected query will have the same value) or a **variable value** (e.g. a value from a different element). To do that, type the “**%**” sign and Mergado will offer you a list of available elements. To finish, click *Create* (step 6)
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/new-rule-variable-content.png)
**Important**! To confirm and implement the changes, you need to click *Apply rules* (image 17).
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/apply-rules.png)
So now you have your changes implemented in the output feed. They will reflect in your product campaign **after** an **automatic synchronization** with a respective comparison shopping service. However, you are able to **force an immediate synchronization manually**. Just go to export **Settings** and click *Regenerate export* (image 18).

## Working with Mergado apps
Mergado apps **expand the possibilities** and reach **of Mergado** itself. With their help, you can easily manage bidding or edit product images in your campaigns. All apps can be found in [Mergado store](https://store.mergado.com/). A link to Mergado Store can be found in the main menu when you log in to your Mergado account (image 19).
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/mergado-store-link.png)
The link navigates you to [Mergado Store](https://store.mergado.com/) page with a list of **available apps** and their basic information (image 20).
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/mergado-store.png)
You can click on any app to see a more **detailed description** (image 21). Here you can learn what the app can do, it’s **price and trial period** etc. To activate it, use the green “**Manage app**” button, or the “**Activation & administration**” link in the app menu.
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/fie-detail.png)
On the app administration page, you can choose for which export you want to activate the app. To activate, **mark the checkbox** on the right and click **Save changes** below (image 22).
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/fie-detail-activate1.png)
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/fie-detail-activate2.png)
Now to start working with the app, go to your export **Summary** page. Here you can see the ***activated app* icon** below the main menu as well as mini info-box in the active apps section (image 23).
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/active-apps.png)
Clicking any of the above links will navigate you to the actual app page, where you can **start working with the app** (image 24).
