-# Note on Image Previews
-# For those wanting image previews, like this system, there are four steps to
-# set it up. These are done automatically for LARBS users, but I will state
-# them here for others doing it manually.
-#
-# 1. chafa must be installed.
-# 2. The scope file (~/.config/lf/scope for me), must have a command similar to
-#    mine to generate chafa images.
-# 3. A `set cleaner` line as below is a cleaner script.
-# 4. lf should be started through a wrapper script (~/.local/bin/lfub for me)
-#    that creates the environment for ueberzug. This command can be be aliased
-#    in your shellrc (`alias lf="lfub") or if set to a binding, should be
-#    called directly instead of normal lf.
+# note: see .config/lf/scope for preview requirements
 
 # Basic vars
