||
## Installation
|
||
|
||
If [available in Hex](https://hex.pm/docs/publish), the package can be installed as:

||
def deps do
|
||
[{:readability, "~> 0.4"}]
|
||
end
|
||
```
|
||
|
||
2. Ensure readability is started before your application:
|
||
|
||
```elixir
|
||
def application do
|
||
[applications: [:readability]]
|
||
end
|
||
```
|
||
|
||
