Expand the info path of Emacs

In Emacs, you can use M-x info to open the manual that comes with Emacs. However, you often have your own document in Info format, for example, the info of auctex is not released with Emacs.
If you want to read your info document, you can add your info path to the Info-directory-list variable:
(Add-to-list 'info-directory-list "~ /Emacs/INFO ")
In this way, when you use M-x info to open the info of Emacs, emacs will automatically help you ~ All documents under the/Emacs/info directory are imported.
