## I18n

By default, your rails application must be configured to `pt-Br`.

If you need to customize some message or field label, you can override the content of pt-Br.yml file.

## Development - With Docker

You needs to build docker container like above:

    $ docker-compose build

You can run all RSpec specs using:

    $ docker-compose run --rm br_danfe rspec


## Development - Without Docker

You needs to install all necessaries dependencies using bunder like above:

    $ bundle install


You can run all RSpec specs using:

    $ bundle exec rspec


## About tests

> If you modify something that caused general visual changes at output pdf's, so you have to rebuild the fixtures pdf files.
>
> You can do this simply deleting the fixture pdf file. The `have_same_content_of` matcher will recreate the fixture in the next time you run the `bundle exec rspec` command.


## Environment variables
