+### Common workflows
+A common workflow, as documented [here](https://docs.gusto.com/embedded-payroll/docs/onboard-a-company), is to create a
+new partner managed company. In this section we will illustrate using a system access token to create a partner managed
+company. Then use the returned company access token for further requests. We'll do this in the following steps.
+1. [Create a Partner Managed Company](https://github.com/Gusto/gusto-python-client/blob/main/gusto_embedded/docs/sdks/companies/README.md#create_partner_managed)
+2. [View](https://flows.gusto.com/terms) and [Accept](https://github.com/Gusto/gusto-python-client/blob/main/gusto_embedded/docs/sdks/companies/README.md#accept_terms_of_service) Terms of Service]
+3. [Create a Company Location]()

 You can override the default server globally by passing a server name to the `server: str` optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the names associated with the available servers:
