+# Extending templates

+There are a variety of Coder-native features to extend the configuration of your development environments.

+## Workspace agents

+## Resource persistence
+
+The resources you define in a template may be _ephemeral_ or _persistent_. Persistent resources stay provisioned when workspaces are stopped, where as ephemeral resources are destroyed and recreated on restart. All resources are destroyed when a workspace is deleted.
+
+> You can read more about how resource behavior and workspace state in the  [workspace lifecycle documentation](../workspaces/lifecycle.md).
+
+Template resources follow the [behavior of Terraform resources](https://developer.hashicorp.com/terraform/language/resources/behavior#how-terraform-applies-a-configuration) and can be further configured  using the [lifecycle argument](https://developer.hashicorp.com/terraform/language/meta-arguments/lifecycle).
+
+### Example usage
+
+A common configuration is a template whose only persistent resource is the home directory. This allows the developer to retain their work while ensuring the rest of their environment is consistently up-to-date on each workspace restart.

+### Template update policies (enterprise)
+
+Enterprise template admins may want workspaces to always remain on the latest version of their parent template. To do so, enable **Template Update Policies** in the template's general settings. All non-admin users of the template will be forced to update their workspaces before starting them once the setting is applied. Workspaces which leverage autostart or start-on-connect will be automatically updated on the next startup.

 During a workspace start or stop build, one of two errors may lead to a broken state. If the call to `terraform apply` fails to correctly provision resources, a workspace build has **failed**. If the computational resources fail to connect the agent, a workspace becomes **unhealthy**.
 
-A failed workspace is most often caused by misalignment from the definition in your template's Terraform file and the target resources on your infrastructure. Unhealthy workspaces are usually caused by a misconfiguration in the agent or startup scripts it runs.
