Button to start sequence

Hi ,
I am completly new to arduino so forgive me for my dumb question...
I like to have a arduino run some leds in a sequence when a button is pressed. (Is it true that if you hit the reset button on the board that you can do the same procedure over and over?)
Please help me i can't figure out how to do it...

There should be no need to press the reset button.

There is a need for you to post your code if you want us to help you.
And please use the code button </> so your code looks like this and is easy to copy to a text editor.
