Usage 1. perhaps add: "and commit these changes".
Usage 5. perhaps add: On the right you should see an elapsed time and a message "in progress".
When the process terminates, "in progress" changes to the timer taken.
If the process fails you will see a red cross on the left and receive an email with a link to the process log.
If the process succeeds ... ?? (has not happened for me yet).
page 3: The paragraph "It is recommended to create a separate YAML file ..." does not seem at all helpful.
(I may not be the only package author ignorant of such things.)
Surely you just need to advise the user to copy the file .github/workflows/release.yml from aclib or utils or ...,
(though it may well be the case that this already exists in all packages on GitHub?)
Minimal example: do not see the point of this for a first-time user.
Larger example: "The following example adds a boolean input dry-run ..." implies that this is not the standard example for making a release, although in fact it is.
