can you give me understitching directions for dummies? im having a very hard time getting it..?

im putting a pocket in a jumper and it asks for understitching. apparently i have a mental block and i have not been able to understand any instructions i have found. can you simplify it to step by step of the actual process...

I think we need a little clarification: is this sewing or knitting? (In the US, a "jumper" is a a sort of of overdress usually sewn from fabric; in the Uk, Australia, and other Commonwealth countries, ia "jumper" is usually a warm outergarment knitted from yarn.) In the meantime, have you tried googling "understitching," perhaps along with "pocket"?
