-Build a typed node graph that processes data through a sequence of operations and produces a final result
-
-## Setup
-
-**Dependencies:**
-
-```text
-pip install blacknode >= 0.3.0 Python >= 3.11 NVIDIA NIM API key (optional but recommended) Anthropic, OpenAI, or other LLM models
-```
-
-**Setup steps:**
-
-1. Clone the repository and install dependencies: pip install -e .
-1. Set NVIDIA_API_KEY or other required API keys in .env
-1. Run the example script: python examples/hello_agent.py
-1. For production, configure hardware pairing and deploy via the blacknode CLI
-
-## Key Files
-
-- `examples/converted_nvidia_nim.py - Full graph with Model, Text, LLMAgent, Output nodes`
-- `examples/hello_agent.py - Minimal agent example connecting Literal → LLMAgent → Print`
-- `blacknode/core - Graph and node implementation (internal)`
-
-## Steps
-
-1. Import required modules (blacknode as bn, NIM_MODEL) and ensure API keys are available via require_nim_api_key()
-2. Create a bn.Graph() instance to hold all nodes and their connections
-3. Define individual nodes with specific input/output parameters (e.g., Text node with 'value' input, LLMAgent node with model parameter, Output node with 'value' output)
-4. Connect nodes together using edge definitions (from_port -> to_port) to establish data flow
-5. Execute the graph using g.cook() to run the pipeline and process data through the node chain
-6. Extract the final result from the output node to complete the workflow
-
-## Implementation Details
-
-```python
-g = bn.Graph()
-```
-
-```python
-model = g.node('Model', **{'value': 'nim:meta/llama-3.1-8b-instruct'})
-```
-
-```python
-agent = g.node('LLMAgent', **{model})
-```
-
-```python
-result = g.cook(output, 'value')
-```
-
-## Inputs
-
-- NIM_MODEL constant (e.g., 'nim:meta/llama-3.1-8b-instruct') for the LLM model
-- blacknode package with Graph, Node, and cook functionality
-- Python script defining node types with inputs/outputs and connecting them via edges
-
-## Outputs
-
-- A fully constructed graph with typed nodes and defined connections
-- Executed result (e.g., processed text, summary, or other output) from the final node
-- A reusable pattern that can be adapted to different models, hardware, or task types
-
-## Failure Modes
-
-- Missing or invalid API key (NIM_API_KEY, OPENAI_API_KEY) causing require_nim_api_key() to fail
-- Type mismatch in node connections (e.g., expecting 'value' but receiving 'text') breaking the data flow
-- Model not available or unreachable (NIM_MODEL not found) causing the LLMAgent node to fail
-- Graph execution error due to incorrect edge configuration or circular dependencies
-- Resource exhaustion (e.g., GPU memory) when processing large inputs in the pipeline

+# graph-based-node-workflow
+
+Create and execute typed node graphs for AI/robotics workflows by defining nodes with inputs/outputs and connecting them with edges, then cooking the graph to run the workflow.
+
+## Setup
+
+**Dependencies:**
+
+```text
+pip install blacknode (core Python package) anthropic, openai, docker, petgraph (dependencies) Rust extensions in blacknode-core, blacknode-runtime (optional)
+```
+
+**Setup steps:**
+
+1. Install blacknode with Python 3.11+ and required dependencies
+1. Clone repository and navigate to project directory
+1. Run examples/converted_text_pipeline.py to see basic graph execution
+1. Modify node definitions and edges to create custom workflows
+
+## Key Files
+
+- `examples/converted_text_pipeline.py - basic pipeline pattern`
+- `examples/hello_agent.py - LLM agent workflow pattern`
+- `examples/research_pipeline.py - multi-node research workflow`
+- `blacknode.py - main CLI entry point`
+
+## Steps
+
+1. Step 1: Initialize a bn.Graph() instance to serve as the workflow container
+2. Step 2: Define individual nodes with their required inputs and outputs (e.g., Literal for data, LLMAgent for inference, Concat for combining, Output for final results)
+3. Step 3: Create edges connecting nodes by specifying source from_port and destination to_port for each data flow
+4. Step 4: Execute the graph by calling g.cook() to process the defined workflow and produce results
+
+## Implementation Details
+
+```python
+g = bn.Graph()
+```
+
+```python
+g._edges = [{"from": "model", "from_port": "value", "to": "agent", "to_port": "model"}]
+```
+
+```python
+result = g.cook(output, "value")
+```
+
+## Inputs
+
+- bn.Graph() - the graph container for the workflow
+- Node definitions (Literal, Text, LLMAgent, Concat, Output, etc.) with specified inputs and outputs
+- Edge connections mapping from_port to to_port between nodes
+
+## Outputs

+- Executed workflow results stored in the graph's output nodes
+- Cooked graph ready for inspection, replay, or deployment
+- Potential error states if node dependencies are missing or ports don't match
+
+## Failure Modes
+
+- Missing node dependencies causing undefined variable errors
+- Port mismatch in edge connections leading to no data flow
+- Incomplete graph definition causing cook() to fail
+- Model API key missing or invalid for LLMAgent nodes
