Before I tell you how to play this akali in mid step by step is it very important to
Play passive till level 6 and use youre twilight shroud as much as possible to stay invisible for youre enemy. After youre level 6 you be able to counter a range char by doing youre ult and do damage with youre other skills. Its also important that you stay in youre line and try to outlevel the other chars so you have a huge Benefit.

1) buy a longsword and a health pot, the longsword is extra damage when you trigger youre mark.

2) buy youre boots and sell the sword you dont need it anymore and try to dive youre enemy at 6.

3) after you did 1) , 2) its time to get soms AP stacks by buying Mejai's Soulstealer.

4) then you get The scepter to slow youre enemy and ofc getsome more AP.

5) then to get alot more AP buy Zhonya's Ring ( doesnt exist anymore its now Deathcap)

6) If you got youre deathcap its time for rageblade.

7) And at the end the lich bane (I had only once i could buy it cuz all the other matches i won already =D).
