-# Exorcist Game (Arcane Purge)
+# Arcane Purge
 
-A text-based exorcist game where Bible verses are the spell mechanics. Fight through a gauntlet of escalating demons by matching verse categories to each demon's weaknesses.
+A text-based exorcist game where Bible verses are your weapons against demonic forces. Type verses from Scripture to cast spells, pass memory tests to defeat demons, and unlock progressively more powerful verses as you advance.
 
-> Personal prototype project — functional, but not polished.
+## What It Does
 
-## Gameplay
+Arcane Purge is a terminal-based game that combines Scripture memorization with demon-slaying gameplay:
 
-- Terminal-based combat loop with timer pressure
+- **Verse Casting** - Select a verse, then type it exactly to deal damage to demons. Verses matching a demon's weakness deal double damage.
-- Six escalating demon encounters, each with health, damage, and elemental weaknesses
+- **Memory Tests** - After a successful cast, recall the same verse without looking. Passing delivers a powerful finishing strike.
-- Verse-based spell system: recite verses from the right category (Binding, Healing, Exorcism, Protection, Judgment) to deal damage
+- **Progression** - Start with 4 easy verses. Defeating demons unlocks harder verses and new categories. After 5 demons, Memory Mode activates.
-- Mismatched categories fizzle — read the demon, pick the verse
+- **Scoring** - Points awarded for correct casts, speed bonuses, memory test success, and demon defeats. Deducted for failures.
+- **Hint System** - Press `H` at any input to see the first letter of each word.
 
-## Project Structure
+## Setup and Dependencies
 
-| Path | Description |
+### Requirements
-|------|-------------|
-| `main.py` | Game engine, demon definitions, and combat loop |
-| `data.py` | Verse loading, normalization, and spell resolution |
-| `verses.json` | Verse dataset |
-| `docker/` | Dockerfile and compose for containerized runs |
-| `tests/` | Test suite for verse data and game logic |
 
-## Running
+- Python 3.11+
+- Astral UV (for dependency management)
+- Docker (for containerized deployment)
 
-### Local
+### Install with UV
 
 ```bash
 uv sync
+```
+
+This installs all dependencies listed in `pyproject.toml` (currently `pytest` for testing).
+
+### Install with pip
+
+```bash
+pip install pytest
+```
+
+## How to Run
+
+### Docker (Recommended)
+
+```bash
+cd docker
+docker compose up --build
+```
+
+This builds the game container and starts it in interactive mode. The game runs inside the container with a TTY attached for input.
+
+To run tests inside the container:
+
+```bash
+cd docker
+docker compose run game python -m pytest tests -v
+```
+
+### Direct Python
+
+```bash
 python main.py
 ```
 
-### Docker
+### Running Tests
 
 ```bash
-docker compose -f docker/docker-compose.yml up
+python -m pytest tests/ -v
 ```
 
-## Status
+The test suite includes 34 tests covering data loading, text normalization, verse filtering, similarity matching, hint generation, and game initialization.
 
-Working prototype. Built as an experiment in terminal game design; not actively maintained.

+### Key Modules
+
+| File | Purpose |
+|---|---|
+| `main.py` | Game loop, demon encounters, verse casting, memory tests, scoring, progression |
+| `data.py` | Verse data loading from JSON, category/difficulty filtering, text normalization |
+| `verses.json` | 12 verses across 5 categories (Binding, Healing, Exorcism, Protection, Judgment) |
+| `tests/` | Validation suite ensuring data integrity and game logic correctness |
+
+## Configuration and Environment Variables
+
+### Environment Variables
+
+Copy `.env.example` to `.env` and configure:
+
+```bash
+PYTHON_VERSION=3.12-slim    # Python version for Docker base image
+GAME_PORT=8080              # (Reserved for future web interface)
+```
+
+The game runs without environment variables configured. All game data is embedded in `verses.json`.
+
+### Verse Data Format
+
+Each verse in `verses.json` follows this structure:
+
+```json
+{
+    "id": "binding_001",
+    "text": "Full verse text here.",
+    "category": "Binding",
+    "difficulty": 1,
+    "reference": "Luke 10:19"
+}
+```
+
+### Adding Verses
+
+Append new verse objects to the `verses` array in `verses.json`. Difficulty must be 1-5.
+
+### Adding Demons
+
+Edit the `DEMONS` list in `main.py`:
+
+```python
+{"name": "Demon Name", "health": 100, "weaknesses": ["Binding", "Exorcism"], "damage": 20}
+```
+
+### Code Quality
+
+The project uses Ruff for linting and Hadolint for Dockerfile validation:
+
+```bash
+ruff format .
+ruff check --fix .
+hadolint docker/Dockerfile
+```
+
+All checks must pass before building the container.

-we need to implement the following key features
-- Add 100 more Bible verses (ensure these are the Biblically accurate scriptures and are the ESV or KJV version)
-	- Give the user the option to pick which version from the start screen 
-- Add some dialog lines in between the battles. 
-- Add a tutorial level where a mentor teaches you how to face a demon.
-- Keep these features in the cli version of the game, but go ahead and make a web version of the game so that people can play this from a browser
-	- On the web version, let the user be able to speak out the verses into their mic. We can use whisper.cpp on the backend to transcribe the audio. You can download what models you need, but try to use the bare minimum for now during testing as my internet speed is not great (40-50 Mbps)
-	- The user will need to still be very accurate with the wordings from the verses.
