+Emacs packages should preferably use the Emacs build system
+(@pxref{emacs-build-system}), for uniformity and the benefits provided
+by its build phases, such as the auto-generation of the autoloads file
+and the byte compilation of the sources.  Because there are no
+standardized way to run a test suite for Emacs packages, tests are
+disabled by default.  When a test suite is available, it should be
+enabled by setting the @code{#:tests?}  argument to @code{#true}.  By
+default, the command to run the test is @command{make check}, but any
+command can be specified via the @code{#:test-command} argument.  The
+@code{#:test-command} argument expects a list containing a command and
+its arguments, to be invoked during the @code{'check} phase.
+
+The Elisp dependencies of Emacs packages are typically provided as
+@code{propagated-inputs} when required at run time.  As for other
+packages, build or test dependencies should be specified as
+@code{native-inputs}.
+
+Emacs packages sometimes depend on resources directories that should be
+installed along the Elisp files.  The @code{#:include} argument can be
+used for that purpose, by specifying a list of regexps to match.  The
+best practice when using the @code{#:include} argument is to extend
+rather than override its default value (accessible via the
+@code{%default-include} variable).  As an example, a yasnippet extension
+package typically include a @file{snippets} directory, which could be
+copied to the installation directory using:
+
+@lisp
+#:include (cons "^snippets/" %default-include))
+@end lisp
+
+When encountering problems, it is wise to check for the presence of the
+@code{Package-Requires} extension header in the package main source
+file, and whether any dependencies and their versions listed therein are
+satisfied.
