 ### Inputs
 
 - `path`: the location of the Python package to build (*optional*, default: `.`).
+- `skip-wheel`: Whether to skip building the wheel in addition to the source distribution.
+  The only meaningful value is `'true'` (note the quotes – GitHub Actions only allow string inputs) and everything else is treated as falsey.
+  (*optional*, default: `'false'`).
