+Expanded Block Data Objects for Minecraft `data` commands.
+
+This current version is built for Minecraft pre-release 1.19.4-pre1, but translation is pretyy straight forwards between other versions with only minor tweaks required.
+
+This is a server-side mod, and is designed with full compatibility in mind for datapack useage.
+
+## Example Usage:
+Getting a block for use in other data commands
+```hs
+data get block -188 68 985
+```

+```js
+{block_state: {Properties: {east: "true", waterlogged: "false", south: "true", north: "false", west: "false"}, Name: "minecraft:white_stained_glass_pane"}, x: -188, y: 68, z: 985}
+```
+The `block_state` property is designed to have 1-to-1 compatibility with the new 1.19.4 `block_display` entities. This allows block data to be copied to/from real blocks and `block_displays`.
