## Usage

  1. Add ex_guard to your list of dependencies in `mix.exs`:

        def deps do
          [{:ex_guard, "~> 1.1.1", only: :dev}]
        end

  2. Create a file named `.exguard.exs` in your root application directory:
    ```elixir
      use ExGuard.Config

      guard("unit-test")
      |> command("mix test --color")
      |> watch(~r{\.(erl|ex|exs|eex|xrl|yrl)\z}i)
      |> notification(:auto)
    ```
    Look at [.exguard.exs](https://github.com/slashmili/ex_guard/blob/master/.exguard.exs) for more fine-grained config
  3. run `mix guard` as soon as you change any file with above pattern, the test gets executed
