 ### EfficientBlock ([efficient_block.hpp](include/efficient_block.hpp), [efficient_block.cpp](src/efficient_block.cpp))
 **Description**
 
-Todo
+Represents a rectangular block. Scaled down version of the previous `Block`, optimized for current feature set.
 
 **Usage**
 
-Todo
+ - Construct object
+ - Call `xywh` to obtain an efficient representation of the properties, convert it to vertices and draw them
+   - Note: This should be batched for peak performance (see `SlimBlockchainHandler`)
+ - Check if a point is inside the block using `is_inside`
+ - Obtain the dimensions using `width` and `height`
+ - Move the block to a new position using `translate`
+ - Mark the block for removal using `request_removal`
+ - Check if a block has been marked for removal using `needs_removal`
 
 **Constructors and Destructors**
 
-Todo
+- `EfficientBlock()`
+- `EfficientBlock(const EfficientBlock&)`
+- `EfficientBlock(int w, int h, int xoffset, int yoffset)`
+
+  Note that (`xoffset`, `yoffset`) are the coordinates of the lower left corner, with origin in the top left corner of the texture.
