 # Minimal API for `doc_identifier`
 ## Introduction
-The tool can identify blocks and players natively, and also handles falling nodes

-However, the identifier can't “identify” (=open the appropriate entry) custom objects
-because the mod doesn't know which help entry to open (if there is any).
-One example would be the boat object (`boats:boat`) from the boats mod in Minetest
-Game.
-If the player tries to use the tool on an unknown object, an error message is shown.

 ## `doc.sub.identifier.register_object(object_name, category_id, entry_id)`
 Registers the object/entity with the internal name `object_name` to the
 entry `entry_id` in the category `category_id`.
 It is in the modder's responsibility to make sure that both the category and
-entry already exist (use `doc.entry_exists` or depend (optionally or not) on the
-respective mods) at the time of the function call, otherwise, stability can not be
-guaranteed.

 ## Description
-The lookup tool is an useful little helper which can be used to quickly learn more about about one's closer environment.
-It identifies blocks, dropped items and other objects and it shows extensive information about the item on which it is used,
-provided documentation is available.

 ## How to use the lookup tool
-Punch any block or item about you wish to learn more about. This will open up the Documentation System entry of this particular
-item.
-The tool comes in two modes which are changed by a right-click. In liquid mode (blue) this tool points to liquids as well
-while in solid mode (red) this is not the case. Liquid mode is required if you want to identify a liquid.

 ## For modders
-If you want the tool to identify nodes and (dropped) items, you probably don't have to do anything, it is probably already
-supported. The only thing you have to make sure is that all pointable blocks and items have a help entry, which is already
-the case for most items, but you may want to do some testing on “tricky” items. Consult the documentation of the
-Documentation System [`doc`] and Item Documentation [`doc_items`] for getting the item documentation right.

-For the lookup tool to be able to work on custom objects/entities, you have to use the tiny API of this mod, see `API.md`.
