I hope to use org files for my configuration. And I found some use
(require 'org-install), and some use
(require 'org). Any differences?
According to the comments inside
org-install.el in Emacs 26.1: "The file
org-install is obsolete." There is nothing inside that file except some comments about backwards compatibility, a
provide statement and some file-local variables. Therefore, use
(require 'org) to load the main library.
Q: How did I learn about that?
M-x find-library RET org-install RET and read the few lines of code.
