Like button

Hello,

Go to this page:

https://developers.facebook.com/docs/reference/plugins/like/

Set the URL to your blog’s URL, change the parameters as you please, and press Get Code.

If you want the button to appear everywhere on your site, probably the easiest way would be to add a Text widget to your sidebar, and paste the code from the “Get Code” box into it.

I hope this helps!
