-If [available in Hex](https://hex.pm/docs/publish), the package can be installed
-by adding `ha_handler` to your list of dependencies in `mix.exs`:
+You'll need the [elixir](https://elixir-lang.org/) toolchain available.
 
-```elixir
-def deps do
-  [
-    {:ha_handler, "~> 0.1.0"}
-  ]
-end
 ```
-
-Documentation can be generated with [ExDoc](https://github.com/elixir-lang/ex_doc)
-and published on [HexDocs](https://hexdocs.pm). Once published, the docs can
-be found at [https://hexdocs.pm/ha_handler](https://hexdocs.pm/ha_handler).

+cd ha-handler/
+mix deps.get
+iex -S mix
