You do not need to find a formula to follow. Basic bread is only four ingredients (three if you omit the salt).
Learn how to use baker's percentages and you can adjust the amount of ingredients to suit your taste. Search for baker's percentages and you get lots of info, but basically it's a system that bakers use to standardize formulas so that they can be scaled up or down easily.
Flour is always 100%, and every other ingredient is a percentage of the flour. Start with 70% hydration for your first loaf (hydration is the term for the percentage of liquid in the dough). Salt is usually 2% and yeast is 1% or less. You need to use a scale to get accurate measuring results and use grams because it much easier to work in units of 10's than 1/4 cups etc.
Start with a 500g flour, 350g water (70%), 1g salt (or not) and 1/2g yeast. Next batch change the water if you want but leave the others the same (if you omit the salt you will want to adjust the yeast down as salt is inhibits the yeast).
