+Hi folks, this is my first contribution to the project.  I'm new to\r
+the git workflow, so go easy on me.  I also know next to nothing about\r
+elisp.  ;-)\r
+\r
+I work for Google, which strongly supports employees contributing to\r
+OSS projects.  Some minor legal red tape must occur because it must be\r
+clear that Google is the legal entity that owns whatever rights (and\r
+liabilities!) exists for the work I do.  So, I use\r
+marmstrong@google.com and not my personal mail, and the contributor\r
+line should say Google and not "Matt Armstrong".  Of course, given\r
+this is a GPL project, those rights are limited and well defined.\r
+\r
+I can, if needed, supply whatever "Contributor License Agreement" is\r
+needed if notmuch maintains these (as the FSF does with what they\r
+typically call "papers").\r
+\r
+My goal here is to make the out-of-box experience better for\r
+notmuch.el users with respect to the choice of faces.  I find that on\r
+terminals with few colors the fonts used by notmuch are often bad\r
+(e.g. black text on a black background).  I had a heck of a time\r
+figuring out how some of these face choices were made.  I want to both\r
+improve the default faces and make them easier to discover and\r
+customize.\r
+\r
+Trivia: I wrote https://github.com/matta/rubymail 15 years ago before\r
+I joined Google.  RubyMail was used by "sup" after sup's author\r
+interned at Google and learned the power of the tags+threading+search\r
+email model.  And then, sup inspired notmuch.  If you squint hard\r
+enough you could say I'm already a notmuch contributor, it is just\r
+that all the code I wrote has been deleted.  ;-)\r
