As they said, no coding at all.
Your mastery tree states that it is 9/21/0, yet in the mastery chapter you state you have 21 in utility and only 8 in defence. Lots of mistakes.

think for all, you should just work on coding first. for instructions, check out jhoijhoi's guide on making a guide. you should also add in situational items like bloodthirster to replace wriggles lantern during the late game phase.

Is a nice start to build Olaf, but your guide is just weird dude.
No BBCoding, no images, or videos, Nishtha said it to you, c'mon man i know that you can do it better :)

Did the same thing I did when I started - No color, formatting, pics, videos, etc. There is a link to JhoiJhoi's guide to making a guide here on Mobafire in My sig that I think would really help with first impressions. You could have the best build and most insightful information described here within your guide, but if the readers don't like it at first glance they probably won't be willing to sift through the wall of text. If you polish it up, I would be happy to come back and +vote it. If you have any questions just PM me.
