Using Web Fonts is very easy, after choosing a font, you just have to place the code in the appropriate file on your site.

So, for those who are confused what font to use, here's a list of some of the best fonts for body and for headlines.
Web Fonts for Body Text
Roboto was designed by Christian Robertson. Since the introduction of Roboto as main font in Android OS, the font quickly became popular. Most of the site use Roboto as primary font.
Source Sans Pro
Designed by Paul D. Hunt, Source Sans Pro is Adobe's first Open source typeface family. This sans-serif font has 12 variants and is best to use in body text.
Merriweather is a slightly condensed font designed by Eben Sorkin. The font has 4 variants, Light, Regular, Bold and Black with each weight having italic styles. Merriweather is designed for bettering text readability.
Droid Sans is a sans-serif typeface designed by Steve Matteson. Droid Sans is a font designed to be used in User interfaces.
Lato is an Open-source font designed by Łukasz Dziedzic in 2010. Lato has five weights with their corresponding italic styles.
When working on Lato, Łukasz tried to carefully balance some potentially conflicting priorities. He wanted to create a typeface that would seem quite “transparent” when used in body text but would display some original traits when used in larger sizes. He used classical proportions (particularly visible in the uppercase) to give the letterforms familiar harmony and elegance. At the same time, he created a sleek sans-serif look, which makes evident the fact that Lato was designed in 2010 — even though it does not follow any current trend.
Designed by Julieta Ulanovsky, Montserrat only contains Regular weight. If you are looking for a free alternative for Gotham or Proxima Nova, then Montserrat is the closest you can get.
Web Fonts for Headlines
Fjalla One is a condensed, medium contrast bold font designed by Sorkin Type. The font is suitable for use in headlines.
Raleway is one of my favorite fonts. This display typeface is inspired by more geometric sans-serif typefaces, and has 9 weights.
