+This GHA expects `cover.out` to be present in the root of your repo at runtime. `cover.out` is usually generated by `go test` when passing the `-coverprofile=cover.out` flag:
 
-- `cover.txt` is the output of `go tool cover -func=cover.out -o cover.txt`
-- `cover.html` is the output of `go tool cover -html=cover.out -o cover.html`
+```sh
+go test -coverprofile=cover.out ./...

-Both `go tool cover` commands can be configured to your liking. For examples on how you might do that you can peak at [`Makefile`](go-test-app/Makefile), or some of my other go projects like [`pretender`](https://github.com/kilianc/pretender/blob/main/Makefile#L44-L57) and [`base-go-cli`](https://github.com/kilianc/base-golang-cli/blob/main/Makefile#L76-L92).

+Once your test has ran and `cover.out` has been generated, the GHA does the following:
 
 1. Create and push [new orphan branch](https://github.com/gha-common/go-beautiful-html-coverage/tree/cover) if one doesn't exist.
+1. Generate `cover.html` and `cover.txt` from `cover.out`.
 1. Customize `cover.html` and rename it `<sha>.html`.
 1. `git-push` the `<sha>.html` file to the orphan branch. This will trigger a `GitHub Pages` deployment.
 1. Post a comment to your PR with your code coverage summary (`cover.txt`) and a link to your `<sha>.html`.
