GNU license on software - web page

[Ivan Sas]

Hello,

 

I have made some web page using Ruby on Rails.

Is it possible to put the code I have made to the GNU license?

The code is easy and it doesn't bring any news, but I want to show to the people that the code is open.

I want to rather make a good gesture and show that my goals are rather open and want from the people visited my page to be open too.

Do you know any similar example?

 

Thank you a lot,

Ivan Sas
