Chia seed flour is surprisingly easy to use in baking. The ratio to regular flour is 1:1 so there is no need to worry about screwing this part up. Baking time is suggested to be 3% longer when using chia seed flour. However that depends on how much chia flour you are using in your recipe. For example, in the recipe below, I used 50/50 chia flour and whole wheat flour so my baking time did not need any adjustments.
