## Setting Up OctoFetch

If you want to create a downloader utility for a particular GitHub repository, you can use this library
to take care of all of the boilerplate, validation, and archive extraction. For example, if you want to create
a downloader for Litestream, you can do the following:

```elixir
defmodule LiteStream.Downloader do
  use OctoFetch,
    latest_version: "0.3.9",
    github_repo: "benbjohnson/litestream",
    download_versions: %{
      "0.3.9" => [
        {:darwin, :amd64, "74599a34dc440c19544f533be2ef14cd4378ec1969b9b4fcfd24158946541869"},
        {:linux, :amd64, "806e1cca4a2a105a36f219a4c212a220569d50a8f13f45f38ebe49e6699ab99f"},
        {:linux, :arm64, "61acea9d960633f6df514972688c47fa26979fbdb5b4e81ebc42f4904394c5c5"}
      ],
      "0.3.8" => [
        {:darwin, :amd64, "d359a4edd1cb98f59a1a7c787bbd0ed30c6cc3126b02deb05a0ca501ff94a46a"},
        {:linux, :amd64, "530723d95a51ee180e29b8eba9fee8ddafc80a01cab7965290fb6d6fc31381b3"},
        {:linux, :arm64, "1d6fb542c65b7b8bf91c8859d99f2f48b0b3251cc201341281f8f2c686dd81e2"}
      ]
    }

  # You must implement this function to generate the names of the downloads based on the
  # user's current running environment
  @impl true
  def download_name(version, :darwin, arch), do: "litestream-v\#{version}-darwin-\#{arch}.zip"
  def download_name(version, :linux, arch), do: "litestream-v\#{version}-linux-\#{arch}.tar.gz"
end
```

You would then be able to download the release artifact by doing the following:

```elixir
iex (1) > Litestream.Downloader.download(".")
{:ok, ["./litestream"], []}
```

## Attribution

It wouldn't be right to not include somewhere in this project a "thank you" to the various projects and people that
helped make this possible:

- The logo for the project is an edited version of an SVG image from the [unDraw project](https://undraw.co/)
- The work done in [Phoenix Tailwind](https://github.com/phoenixframework/tailwind) served as a baseline for how to
  structure this library.
