+#### padrino
+
+For Padrino, slight adjustments needs to be made. Since there are many database
+adapters supported, instead of creating configuration for each one, the
+`DATABASE_URL` environmental variable is provided. You need to parse it in your
+`config/database.rb` file and properly pass to the configuration options.
+For example, for ActiveRecord:
+
+```ruby
+database_url = ENV['DATABASE_URL'] && ActiveRecord::ConnectionAdapters::ConnectionSpecification::ConnectionUrlResolver.new(ENV['DATABASE_URL']).to_hash
+ActiveRecord::Base.configurations[:production] = database_url || {
+  :adapter => 'sqlite3',
+  :database => Padrino.root('db', 'dummy_app_production.db')
+}
+```
