text formatting

Code can be formatted by using the following markup:

For code use the [code] markup

[code]validates_file_format_of :picture, :in => ["gif", "png", "jpg"][/code] 
validates_file_format_of  :picture, :in => ["gif", "png", "jpg"]

For terminal commands use the [terminal] markup

[terminal]rake db:migrate[/terminal] 
rake db:migrate
