# WaEmbedder
**TODO: Add description**
## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `wa_embedder` to your list of dependencies in `mix.exs`:
```elixir
def deps do
  [
    {:wa_embedder, "~> 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/wa_embedder](https://hexdocs.pm/wa_embedder).
