   - Remove previous kitty-scrollback.nvim Kitten mappings in `kitty.conf`
 
+  - The default mapping keys changed from `ctrl+shift` to `kitty_mod`. The default values for `kitty_mod` in Kitty is `ctrl+shift`.
+    - If you are using the default value for `kitty_mod` of `ctrl+shift`, then no change is needed.
+    - If you are using a different value for `kitty_mod`, then you should correct any potential mapping conflicts that may occur
+      now that `kitty-scrollback.nvim` is using `kitty_mod`.

   - Migrate any customized configurations to the new format
     - When you define your kitty-scrollback.nvim Kitten configuration, do not use `--config-file` `yourconfigfile.lua`. Instead,
       move the contents of `yourconfigfile.lua` to an entry in the configuration passed to the kitty-scrollback.nvim setup function.
