Shoot a test, tell us what you saw, and get the fix — in order. Compound shooters read a paper tear; recurve and longbow shooters read where a bare shaft lands. Same idea either way: the arrow tells you what to change.
Work top-down. Always flatten the vertical (nock point / rest height) before you chase left-and-right — a vertical problem throws off the horizontal read. Move in small steps (~1/16") and re-shoot after each change. These are the standard starting corrections; your bow is the final judge, so confirm at distance before you trust it.
