+## INSTALLATION
+
+Since the versions on Melpa and Melpa-stable are broken and abandoned versions, you should avoid installing this package from those repositories. Instead you can install manually.
+
+- Clone this repository
+- Add the following in your Emacs config file:
+
+```emacs-lisp
+(add-to-list 'load-path "/path/to/the/cloned/emacs-wttrin")
+(require 'wttrin)
+...
+```
+
+or in use-package format:
+
+```emacs-lisp
+(use-package wttrin
+   :load-path ""/path/to/the/cloned/emacs-wttrin"
+   ...)
+```
+
+Of if you are using straight, the recipe will be similar to:
+
+```emacs-lisp
+(straight-use-package
+ '(wttrin :type git
+		  :host github
+		  :repo "bcbcarl/emacs-wttrin"
+		  :fork (:host github
+				 :repo "cjennings/emacs-wttrin")))
+```
+
+I will contact the Melpa maintainers and update this package with a working version soon.
