+Adding options
 --------------
 
-* Change which files are previewed in the auto preview:
-In ranger/container/file.py
-the constant PREVIEW_BLACKLIST
+* Add a default value in rc.conf, along with a comment that describes the option.
+* Add the option to the ALLOWED_SETTINGS dictionary in the file
+  ranger/container/settings.py.  Make sure to sort in the new entry
+  alphabetically.
+* Add an entry in the man page by editing doc/ranger.pod, then rebuild the man
+  page by running "make man" in the ranger root directory
+
+The setting is now accessible with self.settings.my_option, assuming self is a
+subclass of ranger.core.shared.SettingsAware.

+Adding colorschemes
+-------------------
 
-* Adding colorschemes:
-Copy ranger/colorschemes/default.py to ranger/colorschemes/myscheme.py

+* Copy ranger/colorschemes/default.py to ranger/colorschemes/myscheme.py
+  and modify it according to your needs.  Alternatively, create a subclass of
+  ranger.colorschemes.default.Default and override the "use" method, as it is
+  done in the "Jungle" colorscheme.

     set colorscheme myscheme
