You can load all these pre-installed configuration files just by putting something like :lang The modules, besides declaring the recipe and initializing and configuring the package with use-package!, also typically pin the package to a specific commit. You can inspect these files yourself and learn what they are doing. There are a lot of different initialization files in Doom called modules that do this for you. To use a package in Doom, you must must first declare this intent by writing the declaration (package!. It may give you the same result in this particular case, but this two macro do very different things and they are not equivalent nor interchangeable. It’s probably more convenient to use the first example with the +roam flag. :recipe (:host github :repo “org-roam/company-org-roam” :branch “master”))

:recipe (:host github :repo “org-roam/org-roam” :branch “master”)) instead of obsolete jethrokuan/org-roam repository! Use master branch from org-roam/org-roam repository

The following examples can be used interchangeably but not simultaneously! packages.el You also should not use use-package! org-roam, put your config in an after! form. If you decide to use it, then you should remove package! org-roam. The +roam flag adds some keybindings and a few other things.

Related to this, should I enable the +roam plugging in $DOOMDIR/packages.el?
