 ## Setup
+
+### 1. Install Dependencies
 ```bash
+# Create and activate virtual environment (recommended)
+python3 -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+
+# Install required packages
 pip install -r requirements.txt
+
+# Install Hecate for terminal tools
 git clone git@github.com:NousResearch/hecate.git
 cd hecate
 pip install -e .
+cd ..
 ```
 
+### 2. Configure Environment Variables
+```bash
+# Copy the example environment file
+cp .env.example .env
+
+# Edit .env and add your API keys
+nano .env  # or use your preferred editor
+```
+
+**Required API Keys:**
+- `ANTHROPIC_API_KEY` - Main agent model (get at: https://console.anthropic.com/)
+- `FIRECRAWL_API_KEY` - Web tools (get at: https://firecrawl.dev/)
+- `NOUS_API_KEY` - Vision & reasoning tools (get at: https://inference-api.nousresearch.com/)
+- `MORPH_API_KEY` - Terminal tools (get at: https://morph.so/)
+- `FAL_KEY` - Image generation (get at: https://fal.ai/)
+- `OPENAI_API_KEY` - Optional, for some Hecate features
+
+See `.env.example` for all available configuration options including debug settings and terminal tool configuration.

 ## Toolsets System
 
 The agent uses a toolsets system for organizing and managing tools. All tools must be part of a toolset to be accessible - individual tool selection is not supported. This ensures consistent and logical grouping of capabilities.
