#### IMPORTANT: READ ME BEFORE USING
It is highly suggested that you use [Resent Client](https://reslauncher.vercel.app/) if you aren't already. It provides better performance, FPS, and will allow for a more stable connection to servers.
**IMPORTANT:** Although both Resent Client and the vanilla Eaglercraft client are safe modified copies of Minecraft AOT-compiled to JavaScript, I cannot guarantee that you **will not get flagged by all anticheats.** While gameplay and testing has shown to be relatively stable and free of anticheat flags, more testing is needed to derive a conclusion on whether or not using EaglerProxy with EagProxyAAS is safe.

EaglerProxy and EagProxyAAS does NOT:
- include any Microsoft/Mojang code,
- ship with offline (cracked) support by default,
- store or otherwise use authentication data for any other purpose as listed on the README,
- Unmodified versions will not maliciously handle your login data, although a modified version has the ability to do so. Only use trusted and unmodified versions of both this plugin and proxy.
- and intentionally put your account at risk.
