+
+Build and execute node-based AI workflows with LLM agents and processing nodes
+
+## Setup
+
+**Dependencies:**
+
+```text
+pip install blacknode (core package) anthropic>=0.25 openai>=1.0 petgraph (for graph operations)
+```
+
+**Setup steps:**
+
+1. Install blacknode package: pip install blacknode
+1. Configure model API keys (NIM_API_KEY, OPENAI_API_KEY, etc.) in .env or editor
+1. Create a Graph instance and add nodes with inputs/outputs
+1. Define node connections in g._edges list
+1. Execute with g.cook() to run the workflow and capture results
+
+## Key Files
+
+- `blacknode/blacknode.py (Graph class implementation)`
+- `examples/hello_agent.py (simple LLM agent workflow)`
+- `examples/converted_nvidia_nim.py (NIM model workflow)`
+
+## Steps
+
+1. Initialize a blacknode.Graph instance to create the workflow structure
+2. Add nodes to the graph with defined inputs and outputs (e.g., Literal, LLMAgent, FileWrite)
+3. Define edges connecting nodes to establish data flow between them
+4. Execute the graph using cook() to run the workflow and generate outputs
+
+## Implementation Details
+
+```python
+g = bn.Graph()
+```
+
+```python
+g._edges = [{'from': 'model', 'from_port': 'value', 'to': 'agent', 'to_port': 'model'}]
+```
+
+```python
+result = g.cook(output_node, 'value')
+```
+
+## Inputs
+
+- Model configuration (NIM_MODEL, API keys for NVIDIA NIM, OpenAI, Anthropic)
+- Node definitions with specified inputs and outputs (Literal, LLMAgent, FileWrite, etc.)
+- Data sources (URLs, text content, or other inputs for the workflow)
+
+## Outputs
+
+- Processed results from the final node (e.g., printed text, written files, or generated data)
+- Graph execution status and any errors encountered during execution
+
+## Failure Modes
+
+- Missing or invalid model API key causing graph initialization failure
+- Incorrect node connections or missing edge definitions leading to runtime errors
+- Model not found or unavailable in the specified environment causing execution failure
+- Graph edges not properly defined or mismatched causing cook() to fail
