+# Scope and compliance guidance
+
+This project is an unofficial compatibility layer for running the macOS League of Legends
+client on Linux through Darling. It is not affiliated with, endorsed by, or sponsored by Riot
+Games, Inc.
+
+## Scope
+
+- The project is about compatibility: making the client run, render and behave correctly on
+  Linux.
+- It does not aim to circumvent DRM, anti-cheat, licensing, telemetry, or other platform
+  security controls, and it does not distribute a game client, game assets, or account data.
+- Do not describe or present the project as a tool for evading detection, preventing bans,
+  bypassing DRM, or defeating anti-cheat. Do not promise that an account will not be banned.
+
+## Terminology
+
+Prefer accurate compatibility language:
+
+| Prefer | Avoid |
+|---|---|
+| compatibility issue, client check, platform identity | detection vector, stealth, evasion, bypass |
+| hardware/platform reporting | spoofing, telemetry leak |
+| runtime/launcher fix | anti-cheat bypass |
+
+Technical facts can be described precisely without framing the work as evasion. If a change
+touches a client check or a platform identity, say what it does and why it is needed for
+compatibility.
+
+## Assets and third-party material
+
+- Do not add or link third-party game assets: logos, icons, fonts, screenshots, gameplay
+  audio/video, client files, game data, or account data.
+- Project icons and artwork must be original. Forks must use their own name and icon; see the
+  trademark notice in `README.md` and `NOTICE.md`.
+- Do not commit local prefixes, logs, tokens, captures, or compiled client/runtime binaries.
+
+## Pull requests and issues
+
+- Describe the compatibility problem and the fix. Avoid "stealth", "spoof", "evade",
+  "undetectable", or "unbannable" framing.
+- Maintainers may ask for wording changes before merging. This is about keeping the project's
+  scope accurate, not about hiding technical details.
+- Contributions that add third-party assets or present the project as a DRM/anti-cheat
+  circumvention tool are out of scope for this repository.
