1- Create a cloud 9 ( c9.io ) rails workspace and enter the following command one by one:

git clone git://github.com/cantino/huginn.git
cd huginn/
cp .env.example .env
bundle
mysql-ctl start
bundle exec rake db:create
bundle exec rake db:migrate
bundle exec rake db:seed 

bundle exec rake db:seed <-- cannot download sample. NOTE: The example 'SF Weather Agent' will not work until you edit it and put in a free API key from http://www.wunderground.com/weather/api/ See the Huginn Wiki for more Agent examples! https://github.com/cantino/huginn/wiki

2- finally, you need to change the port number to $PORT and if still not work then change localhost to $IP in the following config file: .env

3- And kick the app by entering:

bundle exec foreman start

now we see the login page. Good to go
