Summarize this article in one sentence.
Hold the wind chime up or find a makeshift way to hang it, such as temporarily knotting a string. Provide wind or strike the chimes to see if they provide the desired sound. Check to see if all the parts hang evenly and securely. Chances are your chimes currently are top-aligned. This means the top of all the chimes hangs from the platform and the striker hits a little below the midline of the longest chime. You can manipulate the chimes and their strings for different sounds.  In a bottom-alignment, the bottoms of the chimes are all level. The strings hanging them are different lengths and the striker hits a little below the center of the shortest chime. In a center-alignment, the striker is even with the center of all the chimes. The string lengths are all different and the tops and bottoms of the chimes don't align. If you haven't run a wire through the top of the suspension platform, you can push a hook into it instead. You may need to use pliers to bend the hook over so it can latch onto the metal chain you use to hang the wind chime. Other options include running one or more of the chime and striker threads through the platform or installing a triangle of hooks to tie together for hanging the wind chime. Stick the chime on a tree branch, from a metal ring or hook, or wherever else it pleases you. Find a location that provides an adequate amount of wind and keep the chime off the ground to achieve the desired sound.
Test the chime. Change the strike zone. Install a metal hook. Find an area to hang the chime.
