Hello Smallwheels and welcome!
of course you can rely on the community helping you in case something doesn't
work, people here are very friendly and active.
Some people mentioned yet the possibility of a usb stick to try out trisquel
before you install it.
If everything works fine, don't be afraid of the installation. It's a very
self-explaining, user friendly routine.
In case some of your hardware is not supported: you will find good advices
for replacements in this forum. Very often also cheap solutions are possible.
Please keep in mind that for free computing it's worth making a few
sacrifices, although we try to avoid them.
