That's a very great idea of yours to create a pdf trying to help others and beginners.

Try adding the most asked things in the beginners section. Here's a few:

-How to secure their wallets such as using ledger nanos and such.
-Types of wallets available (espeically the offline ones such as electrum and mycelium.
-How to buy bitcoins.
-Dangers of keeping bitcoins on an online exchange.

That's all I can think of.
