[Trisquel-users] New install for new Trisquel user

[g . smyli]

Up until this morning I had never heard of trisquel and now it has taken  
space on my hard drive next to Centos7 and Fedora21. Since I am an idealist  
with a deep love of free and open speech, I am hoping that trisquel will  
become my main OS.
My install went very smoothly and a look at /boot/grub/grub.cfg makes me  
expect to see Centos and Fedora presented the next time I reboot also.
So far, I have only installed Zim and keepassx.
Does anyone have any recommendations re locking down my workstation. Does  
Trisquel documentation include a good guide on that subject.
Any thoughts?
