#+BEGIN_SRC emacs-lisp
(require 'eldoc-box)
#+END_SRC

* Usage
Show the documentation of the symbol at point: =eldoc-box-help-at-point=

Show documentation upon hover: =eldoc-box-hover-mode=. Note that you need to enable ElDoc mode for this to work.

** Use with eglot
As of writing this README, eglot doesn't have a public mode hook, use this hook:

#+BEGIN_SRC emacs-lisp
(add-hook 'eglot--managed-mode-hook #'eldoc-box-hover-mode t)
#+END_SRC
