Here is one video, if you need it:

Usually the glueing process is not too hard, just make sure that you distribute the glue evenly on both the sponge and racket. On the racket, make sure that there is glue all the way at the edge, so you do not leave dead spots with less adhesion. Also be fairly quick when you distribute the glue. It dries pretty fast and if you are not careful you may get lumps. Sure you can just remove it if this happens and start all over again, but it is messy
I actually do not like the cutting process. Even after doing it so many times, it is still weird cutting expensive rubbers. Just make sure that you cut flush with the racket edge, do not tilt the scissors or cutting knife. Otherwise you may risk no overhang at all with an "inwards" edge. IMHO it is better to have a tiny overhang for protection.
Besides this, I have given up on cutting a nice edge. It gets jarred anyway, either with scissors or a sharp Swann-Morton knife. I know it doesn't matter, just a mild OCD
I find sharp textile scissors the easiest option.
