+
+From time to time, we receive bug reports pertaining to errors with byte
+compilation.  These seldom have to do with faulty code in the themes: it
+might be a shortcoming of =package.el=, some regression in the current
+development target of Emacs, a misconfiguration in an otherwise exotic
+setup, and the like.
+
+The common solution with a stable version of Emacs is to:
+
+1. Delete the =modus-themes= package.
+2. Close the current Emacs session.
+3. Install the =modus-themes= again.
+
+For those building Emacs directly from source, the solution may involve
+reverting to an earlier commit in emacs.git.
+
+At any rate, if you encounter such an issue please report it: we will

-Hints can appear everywhere, in wildly varying contexts, hence, their
-appearance, by necessity, is a compromise.  However, there are various
-options for making them stand out. First is dimming the surroundings:
-
-#+begin_src emacs-lisp
-(setq avy-background t)
-#+end_src
-
-Dimming works well when you find it difficult to spot hints, any hint.
-Second is limiting the number of faces used by hints:
-
-#+begin_src emacs-lisp
-(setq avy-lead-faces
-      '(avy-lead-face
-        avy-lead-face-1
-        avy-lead-face-1
-        avy-lead-face-1
-        avy-lead-face-1))
-#+end_src
-
-Limiting the number of faces works well with longer hints when you find
-it difficult to identify individual hints, especially with hints
-touching each other.  The first character of the hint will have an
-intense color, the remaining ones the same neutral color.
-
-Third is preferring commands that produce fewer candidates.  Fewer hints
-is less noise: ~avy-goto-char-timer~ is an excellent alternative to
-~avy-goto-char~.
