+# Scope of Project
+At the moment, this project's scope is generally limited outside of adding new content to the game (blocks, mobs, items). We are currently prioritizing stability, quality of life, and platform support over these things.
+
+## Current Goals
+- Being a robust Desktop version of LCE
+- Having proper controller support across all types, brands on Desktop or Desktop-like platforms (Steam Deck)
+- Improving stability as much as possible
+- Fixing as many bugs as possible
+- Enabling Desktop multiplayer options
+  - LAN P2P Multiplayer
+  - Splitscreen Multiplayer
+  - WAN Servers (IP:Port connectivity)
+  - Platform-based P2P Connectivity
+    - Steam Networking
+    - GameDate?
+    - Maybe more?
+- Refining rendering settings, renderer options, as well as reaching rendering parity with true LCE
+- Having workable multi-platform compilation for ARM, Consoles, Linux
+- Being a good base for further expansion and modding of LCE, such as backports and "modpacks".

+# Use of AI and LLMs
+We currently do not accept any new code into the project that was written largely, entirely, or even noticably by an LLM. All contributions should be made by humans that understand the codebase.
+
+# Pull Request Template
+We request that all PRs made for this repo use our PR template to the fullest extent possible. Completely wiping it out to write minimal information will likely get your PR closed.

 - Native builds for platforms other than Windows have not been tested and are most likely non-functional. The Windows nightly build may still run on macOS and Linux through Wine or CrossOver, but that path is unofficial and not currently supported
