+ :line #f)
+ (p [Then, we define the G-expression that will be run as a
+continuous integration job on every commit. This G-expression uses
+,(code [invoke]) from ,(code [(guix build utils)]). Hence, we make it
+available to the G-expression using ,(code
+[with-imported-modules]). In addition, it needs a number of packages
+which we make available using ,(code [with-packages]). And finally,
+within the body of the G-expression, we have commands cloning the git

+user who will own the git repository at the path specified by ,(code
+[repository]). That user will therefore be able to push into the
+repository through ssh or similar. The ,(file [post-receive-hook]) in
+the repository will be managed by guix-forge to trigger a continuous
+integration run on every commit.])
+ (p [And finally, we put everything together in an ,(code

+with ,(code [guile-json-project]) and the laminar service configured
+with a port for the web interface to listen on.])

+should share the network namespace of the host. To us, this means that
+all ports opened by the container will be visible on the host without
+any port forwarding or complicated configuration. The ,(code
+[--share=/srv/git/guile-json]) option shares the git repository we
+cloned earlier, with the container.])

+through its web interface listening on ,(ref
+:url "http://localhost:8080"). You can list and queue jobs on the
+command-line like so:])

+$ laminarc queue guile-json

+ :line #f)
+ (p [That's it! You just set up your own continuous integration
+system and took the first steps to owning your code!])
+ (p [You could easily use the same configuration to configure a
+Guix system instead of a container. To do so, you will have to take
+care of defining the bootloader, file systems and other settings as
+per your needs. The overall configuration used in this tutorial is
+repeated below for your reference.])
