-Description
-- When you place a filter inserter, it reads either the inventory contents or inventory filters on the input side and sets it's filter to those items.
-- Works only until the inserter filter is full (of course).
-- The mode can be changed or disabled in player mod settings on the fly as needed.
+Description:
+- When you place a filter inserter, it reads either the inventory contents or inventory filters on the pickup side and sets its filter to those items.
+- Fills the inserter's filter only until it is full (of course).
+- The mode can be changed or disabled in player mod settings on the fly as needed.
+- Should work with most modded filter inserters.
+
+Notes:
+- Currently does not work if a mod moves the pickup location directly after placing the inserter (for example [Bob's Logistics](https://mods.factorio.com/mod/boblogistics)).
+- Filter gets overwritten when the player places a filtered inserter on a ghost that already has a filter configured. Does not overwrite when placed with bots.
