# Credo [![CI Tests](https://github.com/rrrene/credo/workflows/CI%20Tests/badge.svg)](https://github.com/rrrene/credo/actions?query=branch%3Amaster) [![Inline docs](https://inch-ci.org/github/rrrene/credo.svg?branch=master)](https://hexdocs.pm/credo)



Credo is a static code analysis tool for the Elixir language with a focus on teaching and code consistency.



It can show you refactoring opportunities in your code, complex code fragments, warn you about common mistakes, show inconsistencies in your naming scheme and - if needed - help you enforce a desired coding style.

## Installation and Usage



The easiest way to add Credo to your project is by [using Mix](http://elixir-lang.org/getting-started/mix-otp/introduction-to-mix.html).



Add `:credo` as a dependency to your project's `mix.exs`:



```elixir

defp deps do

  [

    {:credo, "~> 1.7", only: [:dev, :test], runtime: false}

  ]

end

```



And run:



    $ mix deps.get



    $ mix credo

Documentation is [available on Hexdocs](https://hexdocs.pm/credo/)
