I need advice

Hi, I am new to ruby on rails, I am a student of Ing. Infomatica.
the 9th semester.

Ruby on rails practicing, I’ve ever tell I need more information.
I wonder if I can build the gems?
or just experts?
to use a Datagrid is necessary to install a gem?
I am working on linux, ubuntu 14.10
rails 4.2.0
ruby 2.1.2p95 (05/08/2014) [i386-linux-gnu]

Hi Felix,

Since ruby is open source any one can build gem it is limited to experts.To use datagrid it will be easier if you install gem.
