-## 🏗️ Architecture
+## Setup
-
-1. **Ingestion:** Scans `DATA_DIR` for `.md` files.
-2. **Chunking:** Splits documents into 800-character segments with overlap.
-3. **Enrichment:** A DSPy `IngestionAgent` analyzes each chunk to extract:
-    * **Synopsis:** A one-sentence summary.
-    * **Tags:** Plot points, item names, or themes.
-    * **Entities:** Specific NPCs, Locations, or Factions.
-4. **Vector Store:** Chunks and metadata are embedded using `text-embedding-qwen3` and stored in a local **Turso** database.
-5. **Interactive RAG:** A terminal loop that uses **ReAct (Reasoning and Acting)** to answer queries based on retrieved context.

-## 🛠️ Setup
 
 ### Prerequisites
 
-* **UV [Link to install here](https://docs.astral.sh/uv/)**
+* **[UV](https://docs.astral.sh/uv/)** — Python package manager
-* **LM Studio:** Running a local server at `localhost:1234` (or your specific IP).
+* **Ollama** — Running a local server (default `localhost:11434`)
-* **Models:** * Inference & Embedding: Configurable for your preference. grab your model in LMStudio and update the conifg
+* **Local Models** — Pull your inference and embedding models with `ollama pull`
