 ## Getting Started
 
-### Default Mode: Accumulative Autonomous
-
-The default interactive mode now uses **accumulative autonomous mode**, which combines the best of interactive and autonomous workflows:
-
-```bash
-# Simply run g3 in any directory
-g3
-
-# You'll be prompted to describe what you want to build
-# Each input you provide:
-# 1. Gets added to accumulated requirements
-# 2. Automatically triggers autonomous mode (coach-player loop)
-# 3. Implements your requirements iteratively
-
-# Example session:
-requirement> create a simple web server in Python with Flask
-# ... autonomous mode runs and implements it ...
-requirement> add a /health endpoint that returns JSON
-# ... autonomous mode runs again with both requirements ...
-```
-
-### Other Modes
-
-```bash
-# Single-shot mode (one task, then exit)
-g3 "implement a function to calculate fibonacci numbers"
-
-# Traditional autonomous mode (reads requirements.md)
-g3 --autonomous
-
-# Traditional chat mode (simple interactive chat without autonomous runs)
-g3 --chat
-```
-
 ```bash
 # Build the project
 cargo build --release
 
-# Run from the build directory
-./target/release/g3
-
-# Or copy both files to somewhere in your PATH (macOS only needs both files)
-cp target/release/g3 ~/.local/bin/
-cp target/release/libVisionBridge.dylib ~/.local/bin/  # macOS only
+# Run G3
+cargo run
 
 # Execute a task
 g3 "implement a function to calculate fibonacci numbers"

-# Accumulative Autonomous Mode
-
-## Overview
-
-Accumulative Autonomous Mode is the **new default interactive mode** for G3. It combines the ease of interactive chat with the power of autonomous implementation, allowing you to build projects iteratively by describing what you want, one requirement at a time.
-
-## How It Works
-
-### The Flow
-
-1. **Start G3** in any directory (no arguments needed)
-2. **Describe** what you want to build
-3. **G3 automatically**:
-   - Adds your input to accumulated requirements
-   - Runs autonomous mode (coach-player feedback loop)
-   - Implements your requirements with quality checks
-4. **Continue** adding more requirements or refinements
-5. **Repeat** until your project is complete
-
-### Example Session
-
-```bash
-$ cd ~/projects/my-new-app
-$ g3
-
-🪿 G3 AI Coding Agent - Accumulative Mode
-      >> describe what you want, I'll build it iteratively
-
-📁 Workspace: /Users/you/projects/my-new-app
-
-💡 Each input you provide will be added to requirements
-   and I'll automatically work on implementing them.
-
-   Type 'exit' or 'quit' to stop, Ctrl+D to finish

-```
-
-## Key Features
-
-### 1. Requirement Accumulation
-
-Each input you provide is:
-- **Numbered sequentially** (1, 2, 3, ...)
-- **Stored in memory** for the session
-- **Included in all subsequent runs**
-
-This means the agent always has the full context of what you've asked for.
-
-### 2. Automatic Requirements Document
-
-G3 automatically generates a structured requirements document:
-
-```markdown
-# Project Requirements
-
-## Current Instructions and Requirements:
-
-1. create a simple web server in Python with Flask that serves a homepage
-2. add a /api/users endpoint that returns a list of users as JSON
-3. add error handling for 404 and 500 errors
-
-## Latest Requirement (Turn 3):
-
-add error handling for 404 and 500 errors
-```
-
-This document is passed to autonomous mode, ensuring the agent:
-- Knows all previous requirements
-- Focuses on the latest addition
-- Maintains consistency across iterations
-
-### 3. Full Autonomous Quality
-
-Each requirement triggers a complete autonomous run with:
-- **Coach-Player Feedback Loop**: Quality assurance built-in
-- **Multiple Turns**: Up to 5 iterations per requirement (configurable with `--max-turns`)
-- **Compilation Checks**: Ensures code actually works
-- **Testing**: Coach can run tests to verify functionality
-
-### 4. Error Recovery
-
-If an autonomous run fails:
-- You're notified of the error
-- You can provide additional requirements to fix issues
-- The session continues (doesn't crash)
-
-### 5. Workspace Management
-
-- Uses **current directory** as workspace
-- All files created in current directory
-- No need to specify workspace path
-- Works with existing projects or empty directories
-
-## Command-Line Options
-
-### Default (Accumulative Mode)
-
-```bash
-g3
-```
-
-Starts accumulative autonomous mode in the current directory.
-
-### With Options
-
-```bash
-# Use a specific workspace
-g3 --workspace ~/projects/my-app
-
-# Limit autonomous turns per requirement
-g3 --max-turns 3
-
-# Enable macOS Accessibility tools
-g3 --macax
-
-# Enable WebDriver browser automation
-g3 --webdriver
-
-# Use a specific provider/model
-g3 --provider anthropic --model claude-3-5-sonnet-20241022
-
-# Show prompts and code during execution
-g3 --show-prompt --show-code
-
-# Disable log files
-g3 --quiet
-```
-
-### Disable Accumulative Mode
-
-To use the traditional chat mode (without automatic autonomous runs):
-
-```bash
-g3 --chat
-
-# Alternative: legacy flag also works
-g3 --accumulative
-```
-
-This gives you the old behavior where you chat with the agent without automatic autonomous runs.
-
-## Use Cases
-
-### 1. Rapid Prototyping
-
-```bash
-requirement> create a REST API for a todo app
-requirement> add SQLite database storage
-requirement> add authentication with JWT
-requirement> add rate limiting
-```
-
-### 2. Iterative Refinement
-
-```bash
-requirement> create a data visualization dashboard
-requirement> make the charts interactive
-requirement> add dark mode support
-requirement> optimize for mobile devices
-```
-
-### 3. Bug Fixing
-
-```bash
-requirement> fix the login form validation
-requirement> handle edge case when username is empty
-requirement> add better error messages
-```
-
-### 4. Feature Addition
-
-```bash
-requirement> add export to CSV functionality
-requirement> add email notifications
-requirement> add admin dashboard
-```
-
-## Tips and Best Practices
-
-### 1. Start Simple
-
-Begin with a basic requirement, let it be implemented, then add complexity:
-
-```bash
-✅ Good:
-requirement> create a basic Flask web server
-requirement> add a homepage with a form
-requirement> add form validation
-
-❌ Too Complex:
-requirement> create a full-stack web app with authentication, database, API, and frontend
-```
-
-### 2. Be Specific
-
-The more specific you are, the better the results:
-
-```bash
-✅ Good:
-requirement> add a /api/users endpoint that returns JSON with id, name, and email fields
-
-❌ Vague:
-requirement> add users
-```
-
-### 3. One Thing at a Time
-
-Focus each requirement on a single feature or fix:
-
-```bash
-✅ Good:
-requirement> add error handling for database connections
-requirement> add logging for all API requests
-
-❌ Multiple Things:
-requirement> add error handling and logging and monitoring and alerts
-```
-
-### 4. Review Between Turns
-
-After each autonomous run completes:
-- Check the generated files
-- Test the functionality
-- Decide what to add or fix next
-
-### 5. Use Exit Commands
-
-When done:
-- Type `exit` or `quit`
-- Press `Ctrl+D` (EOF)
-- Press `Ctrl+C` to cancel current input
-

-## Technical Details
-
-### Requirements Storage
-
-- Stored in memory (not persisted to disk)
-- Numbered sequentially starting from 1
-- Formatted as markdown list
-- Passed to autonomous mode as `--requirements` override
-
-### History
-
-- Saved to `~/.g3_accumulative_history`
-- Separate from traditional interactive history
-- Persists across sessions
-- Uses rustyline for readline support
-
-### Workspace
-
-- Defaults to current directory
-- Can be overridden with `--workspace`
-- All files created in workspace
-- Logs saved to `workspace/logs/`
-
-### Autonomous Execution
-
-- Full coach-player feedback loop
-- Configurable max turns (default: 5)
-- Respects all CLI flags (--macax, --webdriver, etc.)
-- Error handling allows continuation
-
-## Troubleshooting
-
-### "No requirements provided"
-
-This shouldn't happen in accumulative mode, but if it does:
-- Check that you entered a requirement
-- Ensure the requirement isn't empty
-- Try restarting G3
-
-### "Autonomous run failed"
-
-If an autonomous run fails:
-- Read the error message
-- Provide a new requirement to fix the issue
-- Or type `exit` and investigate manually
-
-### "Context window full"
-
-If you hit token limits:
-- The agent will auto-summarize
-- Or you can start a new session
-- Consider using `--max-turns` to limit iterations
-
-### "Coach never approves"
-
-If the coach keeps rejecting:
-- Check the coach feedback for specific issues
-- Provide more specific requirements
-- Consider increasing `--max-turns`
-
-## Future Enhancements
-
-Planned improvements:
-
-1. **Persistence**: Save accumulated requirements to disk
-2. **Editing**: Edit or remove previous requirements
-3. **Branching**: Try different approaches
-4. **Templates**: Pre-defined requirement sets
-5. **Review**: Show all accumulated requirements
-6. **Export**: Save to requirements.md
-7. **Undo**: Remove last requirement
-8. **Replay**: Re-run with same requirements
-
