-1. If it is a function or method, a description of the return value using the
-   [`@returns`](https://jsdoc.app/tags-returns) tag.
-1. At least one minimal example code snippet using the
-   [`@example`](https://jsdoc.app/tags-example) tag for basic usage. The reader
-   should be able to copy and execute the code snippet with the expected values.
+1. A description, first
+1. [`@param`](https://jsdoc.app/tags-param) tags for each parameter and a
+   [`@returns`](https://jsdoc.app/tags-returns) tag, if the symbol is a

+Module files, or `mod.ts` files, should have the following:
+
+1. A high-level description of the package.
+1. Sections providing brief overviews of the APIs within the package, including
+   minimal example code snippets (without the `@example` tag).
