 ## Fields
 - `name` (required): name of the benchmark
 - `tool` (required): tool used to get benchmark output. One of `["cargo"]`
-- `platform` (required): a string describing the platform
+- `os` (required): a string describing the os
 - `output-file-path` (required): a path to a file containing the output of the benchmark tool
 - `data-out-path` (required): the path where the output of the action should be written
 
+## Metadata format
+
+The benchmark name in the `cargo` benchmarks can be provided as a `/`-separated string with the format `category/key size/name/platform/api`. The key size should be an integer. Some fields in this string can be left blank. Any unspecified or invalid fields will be parsed to `undefined`.
+
 ## Output data format
 
 The output will be written to `data-out-path` in a standardized JSON format:
