-** Rails Server
-By default, doom has disabled stdout from rails server to prevent emacs lag and performance issues.  You can enable by adding:
-
-#+BEGIN_SRC elisp
-;; On ~/.doom.d/config.el
-(setq projectile-rails-custom-server-command nil)
-#+END_SRC
-
-Also, you can change =bundle exec spring rails server= to another command, like docker.
+** Hacks
++ =projectile-rails-custom-server-command= were changed to suppress extraneous output logged
+  to console. This was done to prevent a memory leak where the underlying
+  process would continue logging to an Emacs buffer, which would grow forever.  You can change to default behaviour by
+  setting this variable to =nil=.
