Useful information to include:

• The current documentation shows the methods on the inventory peripheral, but not for the data on the function calls like getItemDetail don't contain documentation. Some properties are easy to understand and use (count, maxCount, displayname), while others seem to be some sort of key or hash (nbt)

I assume that the nbt is a hash so we can compare the hashes of various items, but there should still be a function to read data of some items like the printed paper and such
