-- **Do NOT include input/output variable tables in module or template READMEs.** The registry automatically generates these from the Terraform source (e.g., variable and output blocks in `main.tf`). Adding them to the README is redundant and creates maintenance drift.

+- **Never include parameter listings or input/output variable tables in module or template READMEs.** This includes workspace parameters declared with `coder_parameter`. The registry automatically parses the Terraform source and displays parameters in a dedicated tab on `registry.coder.com`; input/output documentation is also generated from the source. Duplicating these listings in the README is redundant and creates maintenance drift.
