@@ -78,14 +78,20 @@ While developing a typing manifest it might be a good idea to test the result wi
 release the action in question or merge a PR in the catalog. For this you can `POST` the typing manifest you have
 on disk to the binding server using any valid URL for the action in question, for example using
 ```bash
-curl --data-binary @action-types.yml https://bindings.krzeminski.it/pbrisbin/setup-tool-action/v2/setup-tool-action-v2.pom
+curl -F types=@action-types.yml https://bindings.krzeminski.it/pbrisbin/setup-tool-action/v2/setup-tool-action-v2.pom
 ```
 The binding server generates a binding with only the given type manifest and answer with some unique coordinates
 that you can use in a test workflow script. The binding will be available the normal cache time on the binding
 server and locally as long as you do not delete it from your local Maven repository where it is cached. After
 the cache period on the server ended requesting the same coordinates will return a binding as if no typing
 information is available at all.
 
+When writing typings for a new action that is not published yet or a new version with changed inputs / outputs,
+you should also provide the new action manifest, that the generation works with that state using
+```bash
+curl -F [email protected] -F [email protected] https://bindings.krzeminski.it/foo/bar/vX/bar-vX.pom
+```
+
 Once there are any typings in place for the action, the `_Untyped` suffixed class is marked `@Deprecated`, and a class
 without that suffix is created additionally. In that class for each input that does not have type information available
 there will still be only the property with `_Untyped` suffix and nullability according to required status. For each
