+# Entity Modifiers
+This is a fabric mod that adds entity modifiers to Minecraft.
+
+Entity modifiers are similar to item modifiers, except that they work with entities rather than items!
+They are supposed to replace the `data modify entity ...` commands.
+This makes changing entities much more powerful, as we can provide context to what we want to modify.
+- We know what we want to change. This means we can have validation of our input!
+- We can use number providers rather than having to use `execute store ...`. This also means it doesn't limit us to just the integer range, as we are able to use floating point numbers as well!
+- When we are working with text components we can use advanced components such as `score` that resolve properly.
+- Because we are editing direct values and not save data, we can apply this to players as well! This enables player-specific features like hunger.
+
+## Using entity modifiers
+Entity modifiers are JSON files in data packs.
+You can create entity modifiers under the `modifiers/entities` folder in your namespace.
+This structure is similar to what tags and loot tables use.
+Inside the file you can either have one or an array of modifiers, just like in item modifiers!
+The modifiers can be applied using the `entity` command, which follows a similar syntax to the `item` and `data` commands.
