Hello! This is a great guide to overclocking Haswell CPUs! It is very through and there is lots of useful information: http://www.overclockers.com/3step-guide-to-overclock-intel-haswell

Just a note, Intel voids your warranty when you overclock. To be on the safe side you can get the Intel Performance Tuning Protection Plan which covers any damage caused by overclocking. It is only $25, so it is a great deal IMO. http://click.intel.com/tuningplan/

There's no point in getting such plan. They're milking money. You can't buy a midrange part and overclock it to high end performance today, not even from AMD. Intel pre 2008 didn't have warranty voidable by OC. You're also not getting much from overclocking all the time, so check out the voltage options on your motherboard.
