# How to use the API

# What is a Context.

# What is an Output.

### Modules

- _FlowRunner.Compiler_ parses and compiles JSON flows according to the content spec into an internal representation that can be Run.

- _FlowRunner.Run_ takes a compiled flow, a state and a context and returns new state and user IO.

- _FlowRunner.Context_ is a struct that contains context for a run. It contains the channel, contact and .

## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `flow_runner` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:flow_runner, "~> 6.15.1"}
  ]
end
```

## Doing releases

Use the Github UI to create a new release and publish it. Make sure to update the
`mix.exs` and `README.md` version references _before_ publishing otherwise hex.pm
will complain and prevent you from publishing over an already existing released
version.

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/flow_runner](https://hexdocs.pm/flow_runner).
