Create .env file

For security and migratability, we use gem dotenv-rails.

So, create .env file in your project root (= directory where Gemfile is) as follows.

touch /PATH/TO/PROJECT/ROOT/.env

The file defines environment variables called by ENV['KEY'].

.env contains following key and value.

RAILS_DATABASE_USER='username'
RAILS_DATABASE_PASSWORD='password'

ADRESS='smtp.example.com'
DOMAIN='smtp.example.com'
USER_NAME='username@example.com'
