+Recently I've been toying with a literate configuration[^literate] of Emacs. My init.el took a straightforward form:
+[^literate]: https://en.wikipedia.org/wiki/Literate_programming
+
+{{<highlight lisp "linenos=table">}}
+(org-babel-load-file "~/.emacs.d/config.org")
+{{</highlight>}}
+
+And all of my configuration lives in an org-file. This alone gives me very little benefit for now, but in the future, it will make it easier to have it as a dedicated page on this site.
+
+However, one thing completely surprised me: the elfeed configuration. Until now, I used the standard way of configuring feeds with Elisp. It works, but what it is not is readable. A list of:
+
+{{<highlight lisp "linenos=true,linenostart=199">}}
+("https://gideonwolfe.com/index.xml" blog imporant)
+("https://fabiensanglard.net/rss.xml" blog important)
+("https://protesilaos.com/master.xml" emacs)
+{{</highlight>}}
+
+is far from being manageable and requires constant manual labor.
+
+### Elfeed-org
+
+One of the packages expanding capabilities of elfeed is elfeed-org[^elf-org]. It allows configuring the list of feeds with a standard org tree. Since my config is now also an org file, nothing stops me from adding the list as an org-tree inside my config org-file! I set it up via:
+[^elf-org]: https://github.com/remyhonig/elfeed-org
+
+{{<highlight lisp "linenos=table,linenostart=199,hl_lines=7">}}
+*** elfeed-org
+
+#+BEGIN_SRC emacs-lisp
+  (use-package elfeed-org
+  :ensure t
+  :config
+  (setq rmh-elfeed-org-files (list "~/.emacs.d/config.org"))
+  (elfeed-org))
+#+END_SRC
+{{</highlight>}}
+
+Therefore, I am now pointing at the same file to become the data source for elfeed-org as the rest of my config. Just a few lines down, I start to define my list of subscriptions:
+
+{{<highlight org "linenos=table,linenostart=207">}}
+*** Feeds :elfeed:
+
+**** Blogs
+
+***** https://gideonwolfe.com/index.xml      :important:
+***** https://fabiensanglard.net/rss.xml.    :important:
+
+**** Emacs
+
+***** https://protesilaos.com/master.xml     :important:
+{{</highlight>}}
+
+Much more readable! Elfeed-org will ignore the entire outer tree and extract the feeds from leaves under the `:elfeed:` tag.
