Ahora lo unico que hay que hacer es moverlo abajo de el bloque entradas del blog

y listo

Detalles:
podemos editar algunas funciones como:
var pageCount = 5; (numero de paginas que se muestran por pagina)
var displayPageNum = 3; (numero de paginas en la lista)
var firstPageWord = 'First'; (cambiar por Primero, Inicio, etc)
var endPageWord = 'Last'; (cambiar por Último, algún símbolo, etc)
var upPageWord ='Previous'; (cambiar por Anterior, algún símbolo, etc)
var downPageWord ='Next'; (cambiar por Siguiente, algún símbolo, etc)
Page '+thisNum+' of ' (Página - de, o lo que gusten poner)
