# Use source control and environments

Overview of source control and environments in n8n

{% hint style="info" %}
**Feature availability**

* Available on Business and Enterprise plans.
* You must be an n8n instance owner or instance admin to enable and configure source control.
* Instance owners and instance admins can push changes to and pull changes from the connected repository.
* Project admins can push changes to the connected repository. They can't pull changes from the repository.
  {% endhint %}

n8n uses Git-based source control to support environments. Linking your n8n instances to a Git repository lets you create multiple n8n environments, backed by Git branches.

[^1]: In n8n, credentials store authentication information to connect with specific apps and services. After creating credentials with your authentication information (username and password, API key, OAuth secrets, etc.), you can use the associated app node to interact with the service.
