+### Scrapper basics
+
+A scrapper will produce salvage for a damage-able item by calculating the amount of items returned based on items in the
+recipe, and the percentage of durability left on the item. To avoid returning relatively worthless items instead of
+valuable items, `ignoredSalvage` can be configured. If the item is fully repaired, the worthless items will be returned
+as well, but otherwise, only the valuable items are considered as possible salvage. A scrapper will by default only
+salvage damage-able items (same as blacksmiths), but enabling `extendedSalvageEnabled` for a scrapper will allow it to
+salvage any crafting table recipe. Note that to salvage for example planks into wood, four wood will be taken.
+
+When an item is salvaged, EXP will be returned based on enchantments on the item.

+| ignoredSalvage | TARGET_MATERIAL:IGNORED_MATERIAL | The items that should be ignored when calculating partial salvage. Because receiving just the sticks when salvaging a diamond pickaxe is kind of sad, this allows specifying for example: `*_SHOVEL;*_PICKAXE;*_AXE;*_HOE;*_SWORD:STICK` (the default) for ignoring sticks in salvage for shovels, pickaxes, axes, hoes and swords. A `:` character splits selected items and the ignored salvage. Different item specifications are split by a `;` character. Use `,` to split separate ignored salvages, like: `SHIELD:STICK,BOW_STRING` |
