Pages can be specified in the form of comma separated page ranges like 2-13,17 if you need pages from 2 to 13 and page 17. You can use the syntax 20- if you need pages from page 20 to the end of the document.

Once all the options are properly set you can merge the PDF documents by clicking the
Run button. If no error occurs, the progress bar will grow until it is fully colored and a friendly ding sound will tell you that your merged PDF is ready. You can open it by clicking the icon right above the progress bar.
