Can play guitar. Want to progress with singing now

[RachelMyerse]

To have a good singing voice, you'll need to warm up your voice before singing and avoid vocal strain while singing to keep control. Recording yourself, listening for errors, and letting others listen to you sing will also make it easier to improve your singing voice.

1.Relax your vocal chords before you start singing.
2.Don't force the high notes.
3.Drink plenty cool water (not iced) or have hot/warm tea: This is best for your vocal cords because it simply hydrates them and helps clear away excess mucus.
4.Practice breathing deeply.
5.Practice phrasing.
6.Record yourself

Is it hard to play the guitar?
I want to learn how to play the acoustic guitar, but Is it hard. 

So I heard it takes quite a few years, but I just want to learn the basics. I'm not going to take lessons, so is there any websites where I can learn, for free.
