+Make sure to comment your code where possible. To mark nullable methods, use `@Nullable` (and subsequently, `@NonNull`) from the `org.checkerframework.checker.nullness.qual` package.
 
 The nature of our software requires a lot of arrays and maps to be stored - where possible, use Fastutil's specialized maps. For example, if you're storing block state translations, use an `Int2IntMap`.

 ## What can't be fixed
 There are a few things Geyser is unable to support due to various differences between Minecraft Bedrock and Java. For a list of these limitations, see the [Current Limitations](https://wiki.geysermc.org/geyser/current-limitations/) page.
