I was looking at the top ten Lee Sin guides, and saw yours here, so I figured I would tell you my thoughts. This has the potential to be a great guide, it just isn't quite there yet. Hope you can improve some stuff so I change my vote. :-)
+ For having some BBCoding.
- For some of the grammar being bad.
+ For attempting to put tips.
- For your tips not being very good.
+ For trying to be complete.
- For it not being complete. Some of the sections in the guide are one sentence. Explain to me how to farm. Maybe I don't know how to farm.
Just trying to help, sorry if I come of kind of harsh or mean. :-)

The build is nice, just maybe a bit more precise possibly. Also, for the 'Agressive Start', you put 2 pots and the blade, but you are actually only able to get one pot and not two.

^ agreeded with DeathProphetv2 I will rate if you add a little bit more like matchups (even thought I know it is short and simple) Keep it up.

It would be better if it is more precise.Anyway good job
