Inserting a line After finding a line with a specific word

[KevinMcKloud]

Hola =) ...

I have this:

hola eeeeeeeeeeeeeee eeee
seis siete ocho nueve
diez once doce trece catorce
hola aaaaaaaaaaaaaa aaaaaaaaaa
diez once quince veinte
hola bbbbbbbbbbbbbb
me oyen hola si bueno si probando

and I want this:

==================================
hola eeeeeeeeeeeeeee eeee
==================================
seis siete ocho nueve
diez once doce trece catorce
hola aaaaaaaaaaaaaa aaaaaaaaaa
==================================
diez once quince veinte
hola bbbbbbbbbbbbbb
==================================
me oyen hola si bueno si probando
hola siiiiiiiiiiii ya salio, jeje
==================================

So, how do I insert the "======" line
after a search for "hola" word, so
that way i can make 'groups' of info
to manipulate later...
(Also to insert a "=====" at the beginning
of the file, just for the 1st group)

Thanks =]

NR == 1 { print "==============" }
{print }

/hola/ { print "==============" }
