It’s different for everybody. There’s many different ways to go about it, depending on what your given talent is, what kind of music you are interested in, lead guitar or rhythm, whether you want to sing along or just play, and many other factors.
UltimateGuitar.com is an excellent resource. Find a song you like and learn to play it.
Youtube is also an excellent resource. There are tutorial videos to teach you to play all levels of songs.
