-### OpenRouter
+---
 
-Use [OpenRouter](https://openrouter.ai) to access any model:
+## Prerequisites
+
+Before using nanocode (or any DSPy RLM-based program), you need to install the Deno code interpreter:
+
+```bash
+brew install deno
+```
+
+This is required for the RLM's code execution capabilities.
+
+---
+
+## Quick Start
+
+### Option 1: Use as a Modaic AutoProgram
+
+Load and run nanocode directly from the Modaic Hub without cloning:
+
+```python
+from modaic import AutoProgram
+
+# Load the precompiled nanocode agent from Modaic Hub
+agent = AutoProgram.from_precompiled(
+    "farouk1/nanocode",
+    config={
+        "lm": "openrouter/openai/gpt-5.2-codex",
+        "max_iters": 50
+    }
+)
+
+# Run a coding task
+result = agent(task="What Python files are in this directory?")
+print(result.answer)
+```
+
+### Option 2: Run Locally (Interactive CLI)
 
 ```bash
 export OPENROUTER_API_KEY="your-key"
 python nanocode.py
 ```
 
-To use a different model:
+To use a specific model:
 
 ```bash
 export OPENROUTER_API_KEY="your-key"
-export MODEL="openai/gpt-5.2"
+export MODEL="openai/gpt-4"
 python nanocode.py
 ```
 
-## Commands
+---
 
-- `/c` - Clear conversation
+## Configuration
-- `/q` or `exit` - Quit
+
+When using as a Modaic AutoProgram, you can configure these options:
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `lm` | str | `openrouter/openai/gpt-5.2-codex` | Primary language model |
+| `sub_lm` | str | `openrouter/openai/gpt-5-mini` | Sub-LM for reasoning steps |
+| `max_iters` | int | `50` | Maximum agent iterations |
+| `api_base` | str | `https://openrouter.ai/api/v1` | API base URL |
+| `max_tokens` | int | `50000` | Maximum tokens per request |
+| `max_output_chars` | int | `100000` | Maximum output character limit |
+| `verbose` | bool | `False` | Enable verbose logging |
+| `track_usage` | bool | `True` | Track token usage |
+
+Example with custom configuration:
+
+```python
+from modaic import AutoProgram
+
+agent = AutoProgram.from_precompiled(
+    "farouk1/nanocode",
+    config={
+        "lm": "openrouter/anthropic/claude-sonnet-4",
+        "sub_lm": "openrouter/openai/gpt-4.1-mini",
+        "max_iters": 30,
+        "max_tokens": 8000,
+        "verbose": True,
+        "track_usage": False
+    }
+)
+```
+
+---
+
+## CLI Commands
+
+| Command | Description |
+|---------|-------------|
+| `/c` | Clear conversation history |
+| `/q` or `exit` | Quit the application |
+
+---
 
 ## Tools
 
+The agent has access to the following tools:
+
 | Tool | Description |
 |------|-------------|
-| `read` | Read file with line numbers, offset/limit |
+| `read_file(path, offset, limit)` | Read file contents with line numbers |
-| `write` | Write content to file |
+| `write_file(path, content)` | Write content to a file |
-| `edit` | Replace string in file (must be unique) |
+| `edit_file(path, old, new, replace_all)` | Replace text in a file (old must be unique unless `replace_all=True`) |
-| `glob` | Find files by pattern, sorted by mtime |
+| `glob_files(pattern, path)` | Find files matching a glob pattern, sorted by modification time |
-| `grep` | Search files for regex |
+| `grep_files(pattern, path)` | Search files for a regex pattern |
-| `bash` | Run shell command |
+| `run_bash(cmd)` | Run a shell command and return output |

+### Key Classes
+
+#### `RLMCodingConfig`
+Configuration class extending `PrecompiledConfig` for experiment-specific parameters.
+
+```python
+class RLMCodingConfig(PrecompiledConfig):
+    max_iters: int = 50
+    lm: str = "openrouter/openai/gpt-5.2-codex"
+    sub_lm: str = "openrouter/openai/gpt-5-mini"
+    api_base: str = "https://openrouter.ai/api/v1"
+    max_tokens: int = 50000
+    max_output_chars: int = 100000
+    verbose: bool = False
+    track_usage: bool = True
+```
+
+#### `RLMCodingProgram`
+Main program class extending `PrecompiledProgram`. Wraps a DSPy RLM agent with coding tools.
+
+```python
+class RLMCodingProgram(PrecompiledProgram):
+    config: RLMCodingConfig
+
+    def forward(self, task: str) -> dspy.Prediction:
+        # Returns prediction with .answer
+        return self.agent(task=task)
+
+    def get_tools(self) -> dict:
+        # Returns dict of available tools
+
+    def set_tool(self, name: str, tool: callable):
+        # Add or replace a tool
+
+    def remove_tool(self, name: str):
+        # Remove a tool by name
+
+    def reload_lms(self):
+        # Recreate LM objects from current config
+```
+
+#### `CodingAssistant`
+DSPy Signature defining the agent's input/output schema.
+
+```python
+class CodingAssistant(dspy.Signature):
+    """You are a concise coding assistant with access to sub agents."""
+
+    task: str = dspy.InputField(desc="The user's coding task or question")
+    answer: str = dspy.OutputField(desc="Your response to the user after completing the task")
+```
+
+---
+
+## Publishing Your Own Version
+
+If you modify nanocode and want to publish your own version to Modaic Hub:

+# Push to your Modaic Hub repo
+program.push_to_hub(
+    "your-username/my-nanocode",
+    commit_message="My customized nanocode",
+    with_code=True  # Include source code for AutoProgram loading
+)
+```
+
+---
+

Find files on disk matching a glob pattern.\n- `grep_files(pattern: str, path: str, glob: str, max_results: int) -> str` - [EXTERNAL FILESYSTEM] Search files on disk for a regex pattern using ripgrep.\n- `run_bash(cmd: str) -> str` - [EXTERNAL SYSTEM] Run a shell command on the host machine.",

+      "instructions": "The trajectory was generated with the following objective: \nYou are a concise coding assistant.\n\nCRITICAL - Two execution environments exist:\n\n1. INTERNAL REPL (sandbox): Standard Python code you write executes in an isolated sandbox. Variables persist between iterations. Use for data processing, string manipulation, logic, loops, etc.\n\n2. EXTERNAL TOOLS (real system): Functions like read_file(), write_file(), run_bash(), glob_files(), grep_files() execute OUTSIDE the sandbox on the real filesystem and host machine. These have real, persistent side effects.\n\nWhen you need to:\n- Process data, do math, manipulate strings, iterate \u2192 write Python code directly in the REPL\n- Read/write actual files on disk \u2192 call read_file(), write_file(), edit_file()\n- Run shell commands on the host \u2192 call run_bash()\n- Search the codebase \u2192 call glob_files(), grep_files()\n\nDo NOT confuse REPL variables with external files. Reading a file into a variable does not mean the variable updates if the file changes - you must call read_file() again.\n\n\nBased on the REPL trajectory, extract the final outputs now.\n\n            Review your trajectory to see what information you gathered and what values you computed, then provide the final outputs.",
