# `WardrikStore.Ecto.Migration`

Creates the table `WardrikStore.Ecto` keeps keys in. Call it from a migration of your own:

    defmodule MyApp.Repo.Migrations.AddWardrikStore do
      use Ecto.Migration

      def up, do: WardrikStore.Ecto.Migration.up(version: 1)
      def down, do: WardrikStore.Ecto.Migration.down(version: 1)
    end

Each version is one change to the table. When a release adds a version, add a migration that
runs it.

# `down`

```elixir
@spec down(keyword()) :: :ok
```

Drops what `:version` created. Raises `ArgumentError` for an unknown version.

# `up`

```elixir
@spec up(keyword()) :: :ok
```

Creates what `:version` needs. Raises `ArgumentError` for an unknown version.
