 - Objectives.
 - Full support for new 1.20.4 features (score display names, custom score formats)
-- Doesn't require extra dependencies (assuming you're targeting modern versions of Paper)
+- No extra dependencies (assuming you're targeting modern versions of Paper)
 - Packet-level, meaning it works with other scoreboard plugins
 - Supports [Folia](https://github.com/PaperMC/Folia)
 - Fully async. All packet work is done asynchronously, so you can use the library from the main
   thread without sacrificing any performance
 - Automatically works with `TranslatableComponent`s. All components are translated using `GlobalTranslator` for
   each player's client locale and automatically update whenever the player changes it in their settings
+- ViaVersion awareness: automatically detects 1.12.2- on 1.13+ servers connected through ViaVersion and sends them
+  the optimal packets to maximise sidebar line lengths
 
-## Available Packet Adapters
+## Supported server versions
 
-- **modern.** Supports 1.17-1.21.5. Can take advantage of [Paper](https://papermc.io)'s native adventure support to be more efficient.
-- **legacy.** Supports 1.7.10-1.12.2.
-- **PacketEvents.** Supports 1.8+. Requires [PacketEvents 2.0](https://github.com/retrooper/packetevents/tree/2.0) to be shaded or installed as a plugin.
-
-> [!NOTE]  
-> You can add multiple packet adapters, the best one will automatically be picked depending on the server version.
+All Paper and Spigot versions from 1.7.10 to 26.1 are natively supported.
