I created an alternative `phx.gen.html` which creates templates with TailwindCSS. It works fine. I'd like to share it by creating a Hex package `phx_tailwind_generators`. Here is what I have so fare:

```
$ phx_tailwind_generators:main> tree
.
├── README.md
├── lib
│   ├── phx_tailwind_generators.ex
├── mix.exs
├── priv
│   └── templates
│       └── tailwind.gen.html
│           ├── controller.ex
│           ├── controller_test.exs
│           ├── edit.html.eex
│           ├── form.html.eex
│           ├── index.html.eex
│           ├── new.html.eex
│           ├── show.html.eex
│           └── view.ex
└── test
    ├── phx_tailwind_generators_test.exs
    └── test_helper.exs

```

In those templates I use the `tailwind_error_tag/2` helper which is defined here:

```
defmodule ExampleWeb.TailwindHelper do
  use Phoenix.HTML
  import ExampleWeb.ErrorHelpers

  @doc """
  Generates tag for inlined form input errors.
  """
  def tailwind_error_tag(form, field) do
    Enum.map(Keyword.get_values(form.errors, field), fn error ->
      content_tag(:p, translate_error(error),
        class: "mt-2 text-sm text-red-500",
        phx_feedback_for: input_name(form, field)
      )
    end)
  end
end

```

But how do I store this helper definition in the hex package? How do I rename `defmodule ExampleWeb.TailwindHelper do` in a way that it will work in the target system?
