+<a name="Generator+configureTemplateWorkflow"></a>
+
+### generator.configureTemplateWorkflow
+Configures the template workflow based on provided parsing options.
+
+This function performs the following steps:
+1. Parses the input AsyncAPI document using the specified parse options.
+2. Validates the template configuration and parameters.
+3. Configures the template based on the parsed AsyncAPI document.
+4. Registers filters, hooks, and launches the 'generate:before' hook if applicable.
