Sewing Books!
It is helpful to have one or two sewing books to refer to, especially if you prefer written instructions on paper. I will add a few titles here but also highly recommend going to your local library and looking through a few general sewing books to find one with instructions that resonate with you.

if you prefer in-person instructions, more dates for the Introduction to Hand Sewing class will be added for August and September. The class includes how to hand sew on a button.
More Tips
Cut and Relax the Thread
Do not make the thread too long. It tangles more easily and is harder on the end of the thread that will be going through the fabric more times. Generally cut about fingertip to elbow length. Note, if using double thread for button sewing you will cut twice that length.
After cutting your thread (before or after threading on the needle) run it through your fingers a few times. This relaxes the twist and reduces tangling.
Wax can also be used on the thread to further reduce tangling but there are consequences that we will detail elsewhere. This should not be needed with a good quality thread that is not too long.
Threading Needles
For those of us who find it difficult to thread needles, a simple metal threader makes it easier. Instructions to come on how to use them and how to make them last. If you find these awkward to use then consider using self-threading needles. (Threader is here or self-threading needles are here.)
The Fabric, Thread, Needle Trifecta
These all need to work together and each have different types and sizes but for this page we will keep it simple. Generally use a heavier weight thread and needle for heavier weight fabrics (e.g. a canvas jacket), and lighter weight thread and smaller needle size for light to medium weight fabrics.
Use a general purpose sewing needles, also called "sharps". Needles come in different sizes. For hand sewing needles, the smaller the size, the thicker the needle. A pack with sizes 3 and 9 in it will work for most button sewing situations. The 9 is good for most light to medium weight items like button-up shirts. 3 is good for the heavier weight fabrics like canvas.
Use a similar color thread on the other buttons, assuming you're reattaching one of the buttons that came off. Thread comes in weights and different materials. For light to medium weight fabrics try Daruma cotton, Presencia cotton, Gutermann synthetic sew-all, or Gutermann silk. For heavier weight fabrics like canvas try Extra Strong Gutermann synthetic thread or for a nice wool coat Gutermann silk top stitching thread.
To make a knot or not to make a knot, That is the question...
Why would or wouldn't you want to make a knot? There is nothing wrong with using a knot at the end of the thread. If you prefer a knot for a secure anchor then do it. Reasons to not use a knot include reducing a bump or bulk of thread for preference or comfort. Also, some of us have difficulty making the small hand movements required to make a knot. The thread can absolutely be well-secured without a knot. So choose whichever you prefer, or try different methods.
Position the Button
Don't forget to position the button in the correct spot. You can line up the Button placket and use a pin to mark it. Also ensure the button holes are aligned in the right direction, similar to the other button hole directions.
