Hi, I asume you speak spanish but as I do not know that for sure, I answer to you in english. Well, first of all I think you should create a user account for you (and for anyone that might be entitled to use the computer, as you must hace created a root account during the installation process), and then I might think about getting a linux tutorial from the internet. in fact that would be a good choice.
I think that the best place to start looking for that would be the Redhat site (at the site go to the support section and then to the documentation section).
Ps: if you really speak spanish , please let me know so that we can chat in that language if you prefer.
