+By design, Eglot doesn't depend on anything but Emacs.  But there
+_are_ ELPA dependencies to newer versions of so-called "core packages"
+developed _in the Emacs mainline_.  So unless you're using a
+bleeding-edge Emacs, where loading `eglot.el` is all you'd need to do,
+make sure your package system pulls in and loads the newest
+`project.el`, `xref.el`, `eldoc.el`, etc...  In case of trouble `M-x
+find-library` can help you tell if that happened.
