How to correctly start a dirt bike?

I want to know the correct steps to starting a dirt bike and shifting gears. I have a Honda CRF50 and when i shift gears sometimes it wont kick into first but when i pull the lever on the handle then kick it up it goes into first. I don't have to much experience with dirt bikes so can someone please give me the steps to shifting gears (Ex. neutral to first, first to second) and what to do and what not to do to break the bike?

well i have a 80 and a 70 honda good bike well the steps r start out in nertual than 1 than 2 and if u have an automatic thats all u need to go in to ifu have a clutch start in neural 1 than 2 than 3 than 4 if it will not let u brake if u have a clutch go into a lower gear or use front or back brakes good luck hope u have as much fun on urs as i do
