# How to set up a supplementary feed in Meta
In Meta Commerce Manager, you can [add a supplementary feed](https://www.facebook.com/business/help/609872007120910?ref=search_new_417) to your [catalog](https://www.facebook.com/business/help/1275400645914358?id=725943027795860) to enrich your existing feed with additional data. [Create a feed in Channable](/list-advertise/meta/get-started-with-meta.md) so that you can connect it to your supplementary feed in Meta.
Follow these steps to add a supplementary feed in Meta Commerce Manager:
1. Go to [Meta Commerce Manager](https://business.facebook.com/commerce/).
2. Go to **Catalog** **>** **Data Sources** in the navigation menu.
3. At ‘Supplementary feeds’, click on **Add Supplementary feed**.
4. At **Select data feeds to link to**, select the data feed that you want to add more data to.
5. Select **Use a URL or Google Sheets** and copy and paste your Meta [feed URL](/list-advertise/list-on-channels/feeds-faq/how-do-i-get-the-feed-file-url.md) from Channable, which can be found in the [Preview step](/list-advertise/list-on-channels/set-up-a-feed/set-up-a-feed-preview-and-export-step.md) of the feed setup.
6. Add a name for your feed.
7. Select a **default currency**.
{% hint style="info" %}
**Note:** In Channable, we add the currency by default to all the prices in your feed, so the option you select here does not impact your feed.
{% endhint %}
8. Set how often the feed will refresh at **Data feed schedule**.
{% hint style="info" %}
**Note:** Make sure the scheduled time follows your [Channable schedule settings](/get-started/getting-started/create-a-new-project/edit-your-project-schedule-settings.md) closely.
{% endhint %}
8. At the **Primary feed(s) being supplemented** dropdown, make sure that the correct primary feed is selected.
9. Click on **Upload.**
Your supplementary Meta feed from Channable is connected, and the data in your primary feed is updated in Meta Commerce Manager. You can check this in **Catalog > Items**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://helpcenter.channable.com/list-advertise/meta/get-started-with-meta/how-to-set-up-a-supplementary-feed-in-meta.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
