1. Creating/Deleting/Starting/Shutting Down instance
2. Renewing/Resizing instance
3. Creating/Managing different kinds of DNS Records (A,AAA,CNAME,TXT,SRV,MX)
4. Creating Support Tickets
5. Admin panel at /admin - only accessible by user which has admin attribute true (use irb to do this)

Following things need to be done to ensure proper execution:

• Set Environment variable SECRET_KEY_BASE to a secret key(generate via rake secret)
• Set Environment variable DO_SECRET_KEY to your DigitalOcean API Key
• Set Environment variable SMTP_USERNAME and SMTP_PASSWORD to your SMTP server's credential (used for sending emails - password resets, confirmation emails, etc.)
• Execute rake db:setup or rake db:migrate - To Create Database and apply pending migrations
• Execute rake assets:precompile - To precompile assets (necessary if you are running in production and getting a lot of 404s, make sure RAILS_ENV=production before running this command)
• Update the config/database.yml file according to your Database credentials
• Update config/secrets.yml
  • Change app_host according to the domain name your application is running on. This is the domain which PayPal posts the payment confirmation to.
  • app_host in development can be anything but if you wish to test Paypal integration, make sure you have a hostname that is reachable from the internet (use ngrok)
  • Change paypal_host in productioon to https://www.paypal.com if you are sure everything else is working properly
• Execute rake mailman:start
  • To start mailman in background in order to listen to incoming mails such as password's email from DO.
  • Make sure you correctly specify your POP3 email credential inside config/initializers/mailman.rb - by default it is the same as your SMTP credentials
  • Make sure that DigitalOcean is successfully sending you emails containing the instance's password to the email address specified above
  • We then listen for these kinds of email and match them to see if they belong to any instance that a user recently created, if they do match, we send a email with the instance password and other details to the user's email
• Execute rake bin/delayed_job - To start delayed_job in background in order to send new mail in background incase of reply to a ticket.
