runarium 0.1.0

# Runarium Library Usage Summary

## 📦 Installation for Users

When you publish `runarium` to crates.io, users can install it easily:

### 1. Install System Dependencies (One-time setup)

#### macOS
```bash
brew install opencv llvm
export LIBCLANG_PATH="/opt/homebrew/opt/llvm/lib"
export SDKROOT="$(xcrun --show-sdk-path)"
export CPATH="$SDKROOT/usr/include"
export CPLUS_INCLUDE_PATH="$SDKROOT/usr/include/c++/v1:$SDKROOT/usr/include"
```

#### Linux
```bash
sudo apt-get install libopencv-dev clang libclang-dev
export LIBCLANG_PATH=/usr/lib/llvm-14/lib
```

### 2. Add to Project

```bash
cargo add runarium
```

Or in `Cargo.toml`:
```toml
[dependencies]
runarium = "0.1.0"
```

### 3. Use in Code

```rust
use anyhow::Result;
use runarium::generators::route_video::progressive_route_with_config;
use runarium::configs::video_config::RouteVideoConfig;

fn main() -> Result<()> {
    let config = RouteVideoConfig::default();
    progressive_route_with_config(config)?;
    Ok()
}
```

## 🔧 Key Differences from Installing with OpenCV Paths

### ❌ OLD WAY (Manual OpenCV Setup)
Users had to:
1. Find OpenCV installation paths manually
2. Set multiple environment variables
3. Configure build scripts
4. Handle platform-specific paths

Example:
```bash
export OPENCV_INCLUDE_PATHS=/usr/local/include/opencv4
export OPENCV_LINK_PATHS=/usr/local/lib
export OPENCV_LINK_LIBS=opencv_core,opencv_imgproc,...
```

### ✅ NEW WAY (Published Library)
Users only need:
1. Install OpenCV via package manager (brew/apt/vcpkg)
2. Set LIBCLANG_PATH
3. `cargo add runarium`

Much simpler! The library handles OpenCV detection automatically.

## 🎯 User Experience

### Before Publishing (Current)
```bash
# User needs to:
git clone https://github.com/JFKongphop/runarium
cd runarium
# Set up OpenCV paths manually
cargo build
```

### After Publishing (Goal)
```bash
# User can simply:
cargo new my-project
cd my-project
cargo add runarium
# Write code using runarium
cargo run
```

## 💡 Benefits of Publishing

1. **Easy Installation**: Users just `cargo add runarium`
2. **Version Management**: Semantic versioning (0.1.0, 0.2.0, etc.)
3. **Documentation**: Auto-generated at docs.rs
4. **Discoverability**: Listed on crates.io
5. **Trust**: Official Rust package registry
6. **Updates**: Users can upgrade with `cargo update`

## 🎉 Summary

Once published to crates.io, **runarium** becomes:
- ✅ Easy to install (`cargo add runarium`)
- ✅ Well documented (README + docs.rs)
- ✅ Version controlled (SemVer)
- ✅ Discoverable (crates.io search)
- ✅ Professional (Official Rust ecosystem)

Users no longer need to:
- ❌ Clone the repo
- ❌ Set complex OpenCV paths
- ❌ Understand your build system
- ❌ Manage dependencies manually

They just install OpenCV via their system package manager, add your crate, and start coding!
