The first step is to decide if you're building a phoenix application or not. Phoenix is an extremely high quality web framework, and is the suggested pairing with Ash if you expect to be building a web front end, or an API. For this guide, we assume that elixir has already been installed. We will be using a "helpdesk" example throughout the documentation, so if you want to play along with your own application, you'll need to replace various names.
Install the Phoenix installation archive and then create a new Phoenix application. Be sure to look over the options available with `mix help phx.new`, and visit the phoenix [Phoenix Documentation](https://www.phoenixframework.org/) for more information.
3. Add a Registry. A registry is where you list the resources that a given Api has access to. Create `lib/cool_desk/tickets/registry.ex` with the following contents:
7. Resources are static descriptions of behavior, and don't do anything on their own. To give them functionality, we must first add [actions](../concepts/actions.md), and then we will "invoke" those actions through an Api module. The simplest way to start is to use the `defaults` option to create the four default actions. Add the following to your resource.
```elixir
actions do
defaults [:create, :read, :update, :destroy]
end
```
8. Try it out in iex (run your app with `iex -S mix`):
