That looks nice and useful!

Minor issues:

> address@hidden cgit service

Please capitalize titles: “Cgit Service”

“Git”, not “git”.  Also, not hypersuperlatives please.  :-)

So what about this:

  @uref{https://git.zx2c4.com/cgit/, cgit} is a Web interface to Git
  repositories, written in C.  It allows users to look at Git
  repository contents and history through their Web browsers.

> +The following example will configure the service with default values.
> +By default, cgit can be accessed on port 80 (@code{http://localhost:80}).

> address@hidden
> +(service nginx-service-type)
> +(service fcgiwrap-service-type)
> +(service cgit-service-type)
> address@hidden example

Please add a sentence above or below the example like “This example
shows …”.

> address@hidden @asis
> address@hidden @code{css} (default: @code{"/share/cgit/cgit.css"})
> +Url which specifies the css document to include in all cgit pages.

> address@hidden @code{logo} (default: @code{"/share/cgit/cgit.png"})
> +Url which specifies the source of an image which will be used as a logo
> +on all cgit pages.

s/Url/URL/

> address@hidden @code{scan-path} (default: @code{"/srv/git"})
> +A path which will be scanned for repositories.

Rather: “Name of the directory to scan for repositories.”

Can you also rename ‘scan-path’ to ‘repository-directory’ or something
like that?  (Not “path.”)

> address@hidden @code{robots} (default: @code{(list "noindex" "nofollow")})
> +Text used as content for the "robots" meta-tag.

Write ``robots'' (literally) so that Texinfo typesets things correctly.

Could you submit these nginx changes separately for discussion?  We’ll
also need to document them.  Maybe Cc Chris Baines and other nginx
people.

Thanks!
