The Page plugin lets you easily embed and promote any public Facebook Page on your website. Just like on Facebook, your visitors can like and share the Page without leaving your site. You can use the Page plugin for any Page that is not restricted, for example, by country or age.

I suggest you to use the Facebook page plugin.

it is easy to understand and easy to use.
