+
+To request support, do the following:
+
+- If you are using the [Unstructured open source library](/open-source/introduction/overview), 
+  request support by creating a new message in the **#general** 
+  channel in the [Unstructured Slack community](https://short.unstructured.io/pzw05l7).
+- For Unstructured software-as-a-service (Saas) accounts, including legacy pay-as-you-go, 
+  [Starter](https://unstructured.io/pricing) and [Team](https://unstructured.io/pricing) accounts, 
+  email Unstructured Support at [[email protected]](mailto:[email protected]).<sup>*</sup>
+- For Unstructured [Enterprise](/enterprise/overview) accounts, including dedicated instance and in-VPC accounts, 
+  contact your assigned Unstructured Account Executive (AE) or Customer Success Manager (CSM) for access to your 
+  dedicated Customer Support Portal. 
+  If you do not know who your assigned AE or CSM is, 
+  email Unstructured Support at [[email protected]](mailto:[email protected]).<sup>*</sup>
+
+<sup>*</sup> Before contacting Unstructured Support, please ensure that you consult the 
+latest version of the [Unstructured Shared Responsibility Model](/support/shared-responsibility) to check 
+who owns resolution of the issue you are experiencing. If you contact Unstructured Support about an issue for 
+which the Model states that the customer is ultimately responsible, Support could return the unresolved issue 
+back to you and take no further action.
