-# Minimal development test
-
-This is a basic testing environment that contains a bunch of things to test the engine, but it could also be used as a minimal testbed for testing out mods.
-
-## Features
-
-* Basic nodes for mapgen
-* Basic, minimal map generator
-* Lots of example nodes for testing drawtypes, param2, light level, and many other node properties
-* Example entities
-* Other example items
-* Formspec test (via `/test_formspec` command)
-* Automated unit tests (disabled by default)
-* Tools for manipulating nodes and entities, like the "Param2 Tool"
-
-## Getting started
-
-Basically, just create a world and start. A few important things to note:
-
-* Items are gotten from the “Chest of Everything” (`chest_of_everything:chest`)
-* When you lost your initial items, type in `/stuff` command to get them back
-* By default, Creative Mode activates infinite node placement. This behavior can be changed with the `devtest_infplace` setting
-* Use the `/infplace` command to toggle infinite node placement in-game
-* Use the Param2 Tool to change the param2 of nodes; it's useful to experiment with the various drawtype test nodes
-* Check out the game settings and server commands for additional tests and features
-* Creative Mode does nothing (apart from default engine behavior)
-
-Confused by a certain node or item? Check out for inline code comments.
-
-### Example tests
-
-* You can use this to test what happens if a player is simultaneously in 2 nodes with `damage_per_second` but with a different value.
-* Or use the Falling Node Tool on various test nodes to see how they behave when falling.
-* You could also use this as a testbed for dependency-free mods, e.g. to test out how your formspecs behave without theming.
-
-## Random notes
-
-* Experimental/strange/unstructured tests can be found in the `experimental` mod
-* Textures of drawtype test nodes have a red dot at the top left corner. This is to see whether the textures are oriented properly
-
-## Design philosophy
-
-This should loosely follow the following principles:
-
-* Engine testing: The main focus of this is to aid testing of *engine* features, such as mapgen or node drawtypes
-* Mod testing: The secondary focus is to help modders as well, either as a minimal testbed for mods or even as a code example
-* Minimal interference: Under default settings, it shall not interfere with APIs except on explicit user wish. Non-trivial tests and features need to be enabled by a setting first
-* Convenience: Have various tools to make usage easier and more convenient
-* Reproducing engine bugs: When an engine bug was found, consider creating a test case
-* Clarity: Textures and names need to be designed to keep different things clearly visually apart at a glance
-* Low loading time: It must load blazing-fast so stuff can be tested quickly

-# Test Nodes
-
-This mod contains a bunch of basic nodes to test development stuff.
-Most nodes are kept as minimal as possible in order to show off one particular feature of the engine, to make testing stuff easier.
-
-This mod includes tests for:
-
-* drawtypes
-* paramtype2's
-* node properties such as damage, drowning, falling, etc.
-* other random stuff

---[[ Drawtype Test: This file tests out and provides examples for
-all drawtypes in Minetest. It is attempted to keep the node
-definitions as simple and minimal as possible to keep
-side-effects to a minimum.
-
-How to read the node definitions:
-There are two parts which are separated by 2 newlines:
-The first part contains the things that are more or less essential
-for defining the drawtype (except description, which is
-at the top for readability).
-The second part (after the 2 newlines) contains stuff that are
-unrelated to the drawtype, stuff that is mostly there to make
-testing this node easier and more convenient.

-# Pathfinder Tester
-
-Usage:
-
-Use the Pathfinder Tester tool (`testpathfinder:testpathfinder`).
-Here's how it works:
-
-* Place on node: Set destination position
-* Punch: Find path
-* Sneak+punch: Select pathfinding algorithm
-
-Information will be shown in chat. If a path was found, all waypoints
-will be shown for a few seconds.
-
-See `init.lua` for config variables.

-# Test Tools readme
-
-Test Tools is a mod for developers that adds a bunch of tools to directly manipulate nodes and entities. This is great for quickly testing out stuff.
-
-Here's the list of tools:
-
-## Remover
-Removes nodes and non-player entities that you punch.
-
-## Node Setter
-Replace a node with another one.
-
-First, punch a node you want to remember.
-Then rightclick any other node to replace it with the node you remembered.
-
-If you rightclick while pointing nothing, you can manually enter the node and param2.
-
-## Param2 Tool
-Change the value param2 of nodes.
-
-* Punch: Add 1 to param2
-* Sneak+Punch: Add 8 to param2
-* Place: Subtract 1 from param2
-* Sneak+Place: Subtract 8 from param2
-
-Note: Use the debug screen (F5) to see the param2 of the pointed node.
-
-## Falling Node Tool
-Turns nodes into falling nodes.
-
-Usage:
-
-* Punch node: Make it fall
-* Place: Try to teleport up to 2 units upwards, then make it fall
-
-## Entity Rotator
-Changes the entity rotation (with `set_rotation`).
-
-Usage:
-
-* Punch entity: Rotate yaw
-* Punch entity while holding down “Sneak” key: Rotate pitch
-* Punch entity while holding down “Special” key (aka “Aux”): Rotate roll
-
-Each usage rotates the entity by 22.5°.
-
-## Entity Spawner
-Spawns entities.
-
-Usage:
-
-* Punch to select entity or spawn one directly
-* Place to place selected entity
-
-## Object Property Editor
-Edits properties of objects.
-
-Usage:
-
-* Punch object to open a formspec that allows you to view and edit properties
-* Punch air to edit properties of your own player object
-
-To edit a property, select it in the list, enter a new value (in Lua syntax)
-and hit “Submit”.
-
-## Object Attacher
-Allows you to attach an object to another one.
-
-Basic usage:
-* First select the parent object, then the child object that should be attached
-* Selecting an object is done by punching it
-* Sneak+punch to detach selected object
-* If you punch air, you select yourself
-
-Configuration:
-* Place: Increase attachment Y position
-* Sneak+place: decrease attachment Y position
-* Aux+place: Increase attachment X rotation
-* Aux+Sneak+Rightclick: Decrease attachment X rotation
-
-Hint: To detach all objects nearby you (including on yourself), use the
-`/detach` server command.
-
-## Object Mover
-Move an object by a given distance.
-
-Usage:
-* Punch object into the direction you want to move it
-* Sneak+punch: Move object towards you
-* Place: Increase move distance
-* Sneak+place: Decrease move distance
-
-## Entity Visual Scaler
-Change visual size of entities
-
-Usage:
-
-* Punch entity to increase visual size
-* Sneak+punch entity to decrease visual size
