## Adding items
### Special fields
Items can have these fields:
* `_mcl_generate_description(itemstack)`: Required for any items which manipulate their
description in any way. This function takes an itemstack of its own type and must set
the proper advanced description for this itemstack. If you don't do this, anvils will
fail at properly restoring the description when their custom name gets cleared at an
anvil.
See `mcl_banners` for an example.
All nodes can have these fields:
* `_mcl_hardness`: Hardness of the block, ranges from 0 to infinity (represented by -1). Determines digging times. Default: 0
