-This is the official Deviant Mobile Repo.
+# Deviant Mobile Repository
+
+Official source repository for the Deviant Mobile Unity project.
+
+## Project Overview
+
+This repository contains the full Unity game project, including:
+
+- Unity assets and scenes
+- Gameplay and UI scripts
+- Audio, visual, and character content
+- Build and project settings
+- Large binary assets tracked with Git LFS
+
+Because this project uses many large files, Git LFS is required for every developer machine.
+
+## Prerequisites
+
+Install these before cloning:
+
+1. `git` (2.30+ recommended)
+2. `git-lfs` (3.x recommended)
+
+Then initialize LFS once on your machine:
+
+```bash
+git lfs install
+```
+
+## Clone Instructions (Full Working Copy)
+
+Use SSH (recommended):
+
+```bash
+git clone ssh://git@git.uncaptured.co:2222/Uncaptured_co/deviant-mobile.git
+cd deviant-mobile
+git lfs pull
+```
+
+Or use HTTPS:
+
+```bash
+git clone https://git.uncaptured.co/Uncaptured_co/deviant-mobile.git
+cd deviant-mobile
+git lfs pull
+```
+
+Optional full-history LFS fetch:
+
+```bash
+git lfs fetch --all
+```
+
+## Verify Your Clone
+
+Run:
+
+```bash
+git lfs ls-files | wc -l
+```
+
+You should see a large count (thousands of LFS pointers). If files are missing, run:
+
+```bash
+git lfs pull
+```
+
+## Common Issues
+
+- `Not Found [404]` during `git lfs pull`:
+	- Make sure you are on the correct repository remote.
+	- Re-run `git lfs pull`.
+	- If the issue persists for a specific object, contact the repository maintainer.
+
+- Authentication errors:
+	- Confirm your SSH key or HTTPS credentials are valid for `git.uncaptured.co`.
+
+- Slow LFS transfers:
+	- Retry the pull and ensure network/proxy path is stable.
+
+## Notes for Contributors
+
+- Do not commit large binaries outside Git LFS-tracked paths.
+- Keep Unity meta files consistent with assets.
+- Use small, focused commits for easier review and rollback.
