The record

Purpose: BepInEx is a plugin and modding framework for Unity Mono, Unity IL2CPP, and .NET Framework games, including XNA, FNA, and MonoGame.
Features: It provides drop-in installation, built-in configuration and logging, runtime method patching, and in-memory assembly patching.
Patching integrations: Runtime patching uses Harmony, including HarmonyX and MonoMod, while in-memory assembly patching uses Mono.Cecil with UnityDoorstop.

Installation: BepInEx is installed manually by downloading the correct build and placing its contents in the game's root folder.
Build channels: Official binaries are available as stable builds and bleeding edge builds; the docs say stable builds are recommended in most cases and bleeding edge builds tend to be buggier.

License: The project is open source under the LGPL-2.1 license.
Support and guides: The project links to user and developer guides and a Discord server, and its documentation covers installation, configuration, troubleshooting, and plugin development.
