+The continuous integration server at @code{hydra.gnu.org} builds all
+the distribution packages on the supported architectures and serves
+them as substitutes (@pxref{Substitutes}). Continuous integration is
+currently orchestrated by @uref{https://nixos.org/hydra/, Hydra}.
+
+This section describes an Emacs interface to query Hydra to know the
+build status of specific packages, discover recent and ongoing builds,
+view build logs, and so on. This interface is mostly the same as the
+``list''/``info'' interface for displaying packages and generations
+(@pxref{Emacs Package Management}).
+
+The following commands are available:
+
+@table @kbd
+
+@item M-x guix-hydra-latest-builds
+Display latest failed or successful builds (you will be prompted for a
+number of builds). With @kbd{C-u}, you will also be prompted for other
+parameters (project, jobset, job and system).
+
+@item M-x guix-hydra-queued-builds
+Display scheduled or currently running builds (you will be prompted for
+a number of builds).
+
+@item M-x guix-hydra-jobsets
+Display available jobsets (you will be prompted for a project).
+
+@end table
+
+In a list of builds you can press @kbd{L} key to display a build log of
+the current build. Also both a list of builds and a list of jobsets
+provide @kbd{B} key to display latest builds of the current job or
+jobset (don't forget about @kbd{C-u}).
