Code review comment for lp://staging/~josephjamesmills/ubuntu-packaging-guide/udd-intro.rst-line-02

Is there any reason for this change?

Personally I feel the dash adds some more clarity - for example you could have "Ubuntu Distributed Development - Introduction" and "Ubuntu Distributed Development - Getting set up", etc. where the "-" would separate the title from the chapter name or article name.

If we want to make this even clearer, we could make it "Introduction to Ubuntu Distributed Development".
