+# Common Workflows
+
+This section covers common workflows for managing targets, identities, and sessions within Boundary. This section assumes you've already covered the [getting started](/docs/getting-started) section and are familiar with basic Boundary knowledge. This section extends getting started by showing how to accomplish common workflows in the admin console, the command line, and with our [Terraform provider](https://github.com/hashicorp/terraform-provider-boundary).
+
+For more detailed guides on using Boundary please consult our [learn site](TBD).
