When preparing a new release, set the version number:
-1. in config.mk
-2. in elpher.el metadata at the top
-3. in elpher.el definition of elpher-version
+1. in config.mk: VERSION variable
+2. in elpher.el: metadata at the top
+3. in elpher.el: definition of elpher-version
+4. in elpher-pkg.el: second argument to 'define-package'
+
+For anything besides a patch release, a note describing
+the changes should be added to the documentation. In
+the instance that the documentation itself is significantly
+changed, also update the documentation version:
+
+5. in elpher.texi: 'settitle' declaration at the top
+
+After any documentation updates, make sure it builds:
+
+ make elpher.info elpher.html elpher.pdf
+
