+Eldoc Goes Global
+======
+I recently noticed that Emacs 25.1 had added a global variant of the popular `eldoc-mode`, called `global-eldoc-mode`. What’s more - unlike `eldoc-mode`, `global-eldoc-mode` is enabled by default!
+
+This means that you can get rid of all the code in your Emacs config that was wiring up `eldoc-mode` for major modes that support it:
+
+```
+;; That code is now redundant
+(add-hook 'emacs-lisp-mode-hook #'eldoc-mode)
+(add-hook 'ielm-mode-hook #'eldoc-mode)
+(add-hook 'cider-mode-hook #'eldoc-mode)
+(add-hook 'cider-repl-mode-hook #'eldoc-mode)
+```
+
+There are [some reports][1] that `global-eldoc-mode` is causing performance issues in modes that don’t support it. I’ve never experienced this myself, but if you want to disable it you can simply do so like this:
+
+```
+(global-eldoc-mode -1)
+```
+
+Now it’s time to clean up my config! Deleting code always feels so good!
