 1. **Remove all the tags you do not want to modify so you won't have to update the file every time the original is changed in ViaBackwards**. Only the tags present in the NBT file you put into the plugin directory will be taken and merged with the original data.
 1. Say you want to edit item and entity names: Look for `itemnames` and `entitynames`, edit the values you want to change, and save the file.

 ## Adding custom model data
 As explained above, create a new NBT file in the plugin directory. Add a new `itemdata` compound tag. Similar to the `itemnames` field, the key is the registry id of the item (same as in the `itemnames` tag), the value in this case is another compound tag, which can contain a `custom_model_data` number tag. An example of this looks like:

 We'd suggest simply creating a pull request to change the json file mappings if you think different mappings would be more suitable, so they can be changed in ViaBackwards proper.
 
 # JSON Mappings
+## Changing 1.13- item and block mappings
+Item/Block mappings are located inside different json files, e.g. ``1.12 mappings`` for ``1.11 clients`` are located in `item-mappings-1.12.json`.
+You can move them into the plugin folder and directly edit them. Each json file can contain three different types of mappings:
+- `items` for item mappings (raw id:raw data -> new id/data and custom name)
+- `block-items` same as items but will only replace blocks
+- `blocks` internal mappings to fix blockstate issues (mainly used in ViaRewind). DO NOT EDIT THESE UNLESS YOU KNOW WHAT YOU ARE DOING.

 ## Changing 1.16+->1.15 biome mappings
 Similar to the mappings from above, you can move the `biome-mappings.json` file into the plugin folder and directly add mappings for custom biomes to map them to legacy biomes (the static biome names that existed until 1.15.2). Make sure to keep the file up to date with ViaBackwards updates.
