With custom questions:

• create an initializer: touch config/initializers/decidim_questions.rb
• Fill it with the following:

# frozen_string_literal: true

Decidim::QuestionCaptcha.configure do |config|
  config.questions = {
      en: [
          { "question" => "1+5", "answers" => "6,six" },
          { "question" => "The blue hat is what color?", "answers" => "blue" },
          { "question" => "The green hat is what color?", "answers" => "green" },
          { "question" => "The yellow hat is what color?", "answers" => "yellow" },
          { "question" => "The red hat is what color?", "answers" => "red" }

      ],
      es: [
          { "question" => "1+2", "answers" => "3,tres" },
          { "question" => "El sombrero verde es de qué color?", "answers" => "verde" }
      ],
      ca: [
          { "question" => "2+2", "answers" => "4,quatre" },
          { "question" => "El barret verd és de quin color?", "answers" => "verd" }
      ]
  }
end

• Replace the questions for the corresponding locales, if a question is missing in a locale, the default one is used.

• create an initializer: touch config/initializers/decidim_questions.rb
• Fill it with the following:

# frozen_string_literal: true

Decidim::QuestionCaptcha.configure do |config|
  config.api_endpoint = "API_ENDPOINT"
end

Where API_ENDPOINT is an instance of decidim-captcha-api

further configurations:

# frozen_string_literal: true

Decidim::QuestionCaptcha.configure do |config|
  # Type: Hash
  # List of localized questions 
  config.questions = {
    en: [
      { "question" => "1+1", "answers" => "2,two" },
      { "question" => "The green hat is what color?", "answers" => "green" }
