# Assign a farm name to resources
When rebuilding your Sitecore indexes, Coveo for Sitecore creates or updates a set of resources such as sources and security identities in Coveo called a _farm._ These resources are named after a combination of your Sitecore index name and the `Farm name` value you specified in the activation step.
If you have not specified a `Farm name` value, the Sitecore host and instance name are used instead.

**Example**

When activating Coveo for Sitecore, you call your farm `ProductionFarm`.
The first rebuild of the `master` index creates a source called `Coveo_master_index - ProductionFarm` in your Coveo organization.

> **Leading practice**
>
> You should specify a `Farm name` value to unify all [Coveo Platform](https://docs.coveo.com/en/186/) resources under a single label.
> This is also a mandatory step when scaling your Coveo for Sitecore environment (see [Prepare the Main Sitecore Content Manager for a Scaled Environment](https://docs.coveo.com/en/2416/)).
> 
> You can set or update the `Farm name` in the Coveo **Command Center** (see [Modifying your Indexing Options](https://docs.coveo.com/en/2572#modifying-your-indexing-options)).

Updating the `Farm name` appends the same suffix to all sources and security identities.
If you're looking to update only a specific source, see [Change the Name of Sources Created in the Coveo Index](https://docs.coveo.com/en/2164/).

> **Important**
>
> Changing the `Farm name` in the **Command Center** updates the `<farmName>` element text content in `Coveo.SearchProvider.Custom.config`.
> Similarly, when you change the text content of the `<farmName>` element in `Coveo.SearchProvider.Custom.config`, the **Command Center** reflects this change as soon as you refresh the page.
> 
> However, if you overwrite the `Farm name` value using a patch file of your own, the **Command Center** will detect a difference between the `Coveo.SearchProvider.Custom.config` `Farm name` and the one in the Sitecore compiled configuration.
> When both values are different, the **Command Center** disables `Farm name` editing.
