Hi Rahul, I'd recommend you to visit http://gnupdf.org/manuals/gnupdf-hg-manual/html_node/Information-for-Newcomers.html
When you're ready, ask for a flyspray (the task manager) account, jemarch, the maintainer, would do it. Then login to flyspray and you're free to choose any unassigned task and marked as NEXT. welcome and happy hacking! -gerel
