 At minimum, the module must provide the `module_name` and `maintainer` fields.
 
+The `license` field is encouraged to indicate the terms for using and sharing the module. It is recommended to use a [SPDX license identifier](https://spdx.org/licenses/) like "`Apache-2.0`" or "`GPL-2.0-or-later`" if possible.
+
+The `url` field may specify a URL to more information about the module.
+
 The use of `features` matches the definition normally provided within `keyboard.json` and `info.json`, allowing a module to signal to the build system that it has its own dependencies. In the example above, it enables the _deferred executor_ feature whenever the above module is used in a build.
 
 The `keycodes` array allows a module to provide new keycodes (as well as corresponding aliases) to a keymap.
