I'd rather point at https://sourceware.org/gdb/contribute/
and then have _that_ point at some page in the wiki.
That's what I had suggested in the other thread.
The reason is that the <https://sourceware.org/gdb/contribute/>
URL is going to be more stable than a wiki link, which we can
rename, split, etc. a bit more freely.  The contribution checklist page
is quite large by now, and I've heard of people wishing for a smaller more
concise entry point.  The checklist was meant to be that, a checklist.
A "how to contribute" page may have some higher level info to
get people started.

Thanks,
