I had a quick look at your machine and it seems pretty straight forward.
There are two main types of quilting - one uses a 'Walking Foot', to stop the layers of your quilt sliding and is mostly for stitching in straight(ish) lines e.g. along the seam or grid pattern. You would attach this to the shank and there are instructions on YouTube how to do this. Some quilting machines, such as Pfaff have this built in, but most require the purchase of a foot.
The other type of quilting is Free Motion Quilting - FMQ - and for this you will need a darning foot. Thgis has an unusual 'hopping' action. When attached (and the feed dogs on your machine lowered), you will be able to meander across the quilt in any direction.
Most beginners buy a Walking Foot first and by the looks of it, your machine can use a generic foot that fits other brands such as Janome. You can now buy a Walking Foot that will accommodate the fancier, wider quilting stitches, so you may want to check that out too.
Happy quilting!
