The cheat sheet looks OK so far.
However, if you want this to be a full guide, you will have to add - everything.

Introduction

You can add very important information here:

• Who are you? (your summoner name, where you play, ...)
• Why should we listen to you? (your rating, your experience, ...)
• Some very general information about AP Miss Fortune (like, AP Miss Fortune has a huge AoE burst and deletes entire teams if positioned correctly - don't say too much, just give a hint)

Summoner Spells

Come on, really, one sentence?
If I see someone Flash, I can most likely tell which Elo tier they are in - use and choice of summoner spells are vital.

Explain

• What is this spell good for? (crowd control, burst, don't be afraid to name some champions)
• How do you use this spell? (really detailed, imagine I'm level 5 and Flash to get a last hit)
• Optional: How does this spell work with Miss Fortune's kit? (like, you can cast Barrier with Bullet Time)

Laning

"Abilities" and "Lane enemies" (matchups) don't really belong here.
Of course, you will talk about the use of abilities and you will highlight some special opponents, but you should make a separate chapter for abilities and one for matchups (abilities are explained before laning and matchups are explained after laning).

Laning divides into several phases (maybe even more than what I've listed):

• Pre-laning (if you count it to laning)
• Early laning (before level six)
• Mid game (late laning, after level six)

You have to tell your readers exactly what to do in those phases.
Imagine I have no idea what AP Miss Fortune does.
Is she good at roaming? Why?
Does she pick up kills in lane? How?
Does she just farm? For what?
I have no idea, bro, you have to explain it, that's the basic idea.

Additionally, add chapters to explain every part of your cheat sheet:

• Summoner Spells (partially done)
• Runes
• Masteries
• Items
• Skill Sequence (optional, maybe add to "abilities")

And add additional chapters about your champion:

• Pros/Cons (brilliant way to tell your readers what your champion can do)
• Abilities (really, this is what makes champions what they are, explain this)
• Laning (partially done)
• Team fighting (game doesn't end after laning phase)
• Matchups (optional, partially done)
• ... (whatever you want to add, like "Tips and tricks")

This is my opinion on this guide and I'm looking forward to see the complete version.
Tip: Publish your guide when it's done.
You will just get unnecessary downvotes if you publish a guide "under construction".
Keep it private until you're done.
