+[=[Mining (or digging) is the process of breaking blocks to remove them
+
+Some blocks can not be mined, and some blocks can always be mined. Usually, blocks require a certain type of mining tool to be mined. When in doubt, just try out all your available mining tools on a block and see how efficient they are.
+
+Mineable blocks have mining properties (based on groups) and a mining level. Mining tools have the same properties. Each mining property of a block also has a rating, while tools can be able to break blocks within a range of mining ratings.
+
+In order to mine a block at all, these conditions need to be met:
+• The block and tool share at least one mining property for which the have a matching mining rating
+• The tool's mining level is equal or less than the block's mining level.
+
+The time it takes to mine a block depends on the mining ratings and the mining level. Mining usually wears off tools. Mining blocks with a higher mining level will wear out your tools faster.
+
+Example: A block with the mining property “cracky”, rating 3 and level 0 can only be broken by a tool which is able to break “cracky” blocks at rating 3 and it must have a mining level of 0 or larger.
+
+After mining, a block will leave a “drop” behind. This is a set of items you receive in your inventory after mining it. Blocks usually drop themselves. The following drop types are possible:
+• Always drops one or more items
+• Drops items based on probability
+• Drops nothing]=],
