 a new workspace with matching parameters, Coder assigns them an existing prebuilt instance.
 Prebuilt workspaces significantly reduce wait times, especially for templates with complex provisioning or lengthy startup procedures.
 
 Prebuilt workspaces are:
 
 - Created and maintained automatically by Coder to match your specified preset configurations.

 - **Compatible Terraform provider**: Use `coder/coder` Terraform provider `>= 2.3.0-pre2`. (**TODO: update with latest version**)
 - **Feature flag**: Enable the `workspace-prebuilds` [experiment](../../../reference/cli/server.md#--experiments).
