"content": "# Raknetify\nA Fabric mod / Velocity plugin / BungeeCord plugin that uses RakNet to improve multiplayer experience significantly\nunder unreliable and rate-limited connections.\n\n# Features\n- Higher reliability and lower latency under unreliable and rate-limited client connections.\n- Uses RakNet's multiple channels with priorities to achieve higher responsiveness. \n- Supports ViaVersion client-side and ViaVersion server-side.\n\n# How to use it?\n\n## Prerequisites\n- Raknetify is designed to work on Minecraft 1.17.1+\n Note: On proxies such as Velocity and BungeeCord, **unsupported client version** will cause\n multi-channelling failing to initialize, causing **reduced responsiveness**. \n- You need to have a UDP port opened at the same port number of your normal server port. \n\n## Installation and usage\n- Download the latest release from \n [GitHub](https://github.com/RelativityMC/raknetify/releases) \n [Modrinth (Fabric)](https://modrinth.com/mod/raknetify/versions) \n [CurseForge (Fabric)](https://www.curseforge.com/minecraft/mc-mods/raknetify/files)\n [SpigotMC (BungeeCord)](https://www.spigotmc.org/resources/raknetify-bungeecord.102509/)\n or development builds from [CodeMC](https://ci.codemc.io/job/RelativityMC/job/raknetify/)\n- Install the mod on both client and server. (Installation on backend servers are not needed if using on proxies) \n- Prefix your server address with `raknet;` (or `raknetl;` to use high mtu) and save or connect directly. \n (e.g. `raknet;example.com`)\n- Enjoy!\n\n"
