-# Axum Template Usage Guide
-
-This repository is a **cargo-generate** template for creating new Axum web services with a pre-configured, production-ready setup.
-
-## Quick Start
-
-### Prerequisites
-
-Install `cargo-generate`:
-
-```bash
-cargo install cargo-generate
-```
-
-### Generate a New Project
-
-#### From a Git Repository (Recommended for Production Use)
-
-```bash
-cargo generate --git https://gitea.fasharp.io/fa-sharp/axum-template
-```
-
-#### From Local Path (For Testing)
-
-```bash
-cargo generate --path /path/to/axum-template
-```
-
-### Interactive Prompts
-
-When you run `cargo generate`, you'll be prompted for:
-
-1. **Project name**: The name of your new project (e.g., `my-api-server`)
-2. **Project description**: Brief description (e.g., "REST API for user management")
-3. **Environment variable prefix**: Prefix for configuration env vars (e.g., `APP` → `APP_HOST`, `APP_PORT`)
-4. **Default port**: Server's default port (e.g., `8080`)
-5. **Default log level**: Choose from `trace`, `debug`, `info`, `warn`, or `error`
-6. **Include aide**: Whether to include OpenAPI documentation support (`true` or `false`)
-
-### Non-Interactive Mode
-
-You can skip prompts by providing values via CLI:
-
-```bash
-cargo generate --git <repo-url> \
-  --name my-service \
-  --define project-description="My awesome service" \
-  --define env_prefix="API" \
-  --define default_port="3000" \
-  --define default_log_level="info" \
-  --define include_aide=true
-```
-
-## Generated Project Structure
-
-```
-my-project/
-├── src/
-│   ├── main.rs       # Application entry point with server setup
-│   ├── lib.rs        # App initialization and plugin registration
-│   ├── config.rs     # Configuration management (figment-based)
-│   └── state.rs      # Application state management
-├── Cargo.toml        # Dependencies (customized based on your choices)
-├── .env.example      # Example environment variables
-├── .gitignore        # Pre-configured for Rust projects
-└── README.md         # Project-specific README
-```
-
-## Configuration
-
-The generated project uses environment variables for configuration. The prefix is customizable during generation.
-
-Example with `APP` prefix:
-
-```bash
-# Required
-APP_API_KEY=your-secret-api-key
-
-# Optional (defaults are set during template generation)
-APP_HOST=127.0.0.1
-APP_PORT=8080
-APP_LOG_LEVEL=info
-```
-
-In development, copy `.env.example` to `.env`:
-
-```bash
-cp .env.example .env
-# Edit .env with your values
-```
-
-## Features Included
-
-### Core Features (Always Included)
-
-- **Axum 0.8** - Modern, ergonomic web framework
-- **Environment-based Config** - `figment` for flexible configuration
-- **Structured Logging** - `tracing` with JSON output in production
-- **Graceful Shutdown** - Handles SIGTERM, SIGINT, and Ctrl-C
-- **Plugin Architecture** - `axum-app-wrapper` for modular initialization
-- **Rust 2024 Edition** - Latest language features
-
-### Optional Features
-
-- **OpenAPI Documentation** - `aide` and `schemars` (optional during generation)
-
-## Next Steps After Generation
-
-1. **Navigate to your project**:
-   ```bash
-   cd my-project
-   ```
-
-2. **Configure environment**:
-   ```bash
-   cp .env.example .env
-   # Edit .env with your actual values
-   ```
-
-3. **Run in development**:
-   ```bash
-   cargo run
-   ```
-
-4. **Add your routes**:
-   - Create a new module for your routes
-   - Implement a plugin function
-   - Register it in `src/lib.rs`
-
-5. **Build for production**:
-   ```bash
-   cargo build --release
-   ```
-
-## Customization Tips
-
-### Adding Routes
-
-Create a new module (e.g., `src/routes.rs`):
-
-```rust
-use axum::{routing::get, Router};
-use axum_app_wrapper::AdHocPlugin;
-use crate::state::AppState;
-
-pub fn plugin() -> AdHocPlugin<AppState> {
-    AdHocPlugin::new().on_router(|router| async move {
-        let routes = Router::new()
-            .route("/health", get(health_check));
-        
-        Ok(router.merge(routes))
-    })
-}
-
-async fn health_check() -> &'static str {
-    "OK"
-}
-```
-
-Register it in `src/lib.rs`:
-
-```rust
-pub async fn create_app() -> anyhow::Result<(axum::Router, AppConfig, impl Future + Send)> {
-    let (router, state, on_shutdown) = App::new()
-        .register(config::plugin())
-        .register(routes::plugin())  // Add this line
-        .init()
-        .await?;
-    
-    let app_config = state.config.to_owned();
-    Ok((router.with_state(state), app_config, on_shutdown))
-}
-```
-
-### Adding Dependencies
-
-Just edit `Cargo.toml` as normal:
-
-```bash
-cargo add sqlx --features postgres,runtime-tokio
-```
-
-### Changing the Environment Prefix
-
-The prefix is baked in during template generation. To change it later, search and replace in:
-- `src/config.rs` (the `extract_config` function)
-- `.env.example`
-
-## Publishing Your Template
-
-### GitHub
-
-1. Push this directory to GitHub
-2. Enable "Template repository" in Settings
-3. Others can use: `cargo generate --git https://github.com/you/axum-template`
-
-### GitLab/Gitea
-
-1. Push to your instance
-2. Share the URL: `cargo generate --git https://gitea.example.com/you/axum-template`
-
-### Private Repositories
-
-cargo-generate supports authentication:
-
-```bash
-cargo generate --git https://github.com/you/private-template --branch main
-# You'll be prompted for credentials if needed
-```
-
-## Template Maintenance
-
-### Updating Dependencies
-
-Update the versions in `Cargo.toml.liquid` and commit:
-
-```bash
-# Edit Cargo.toml.liquid
-git add Cargo.toml.liquid
-git commit -m "Update dependencies"
-git push
-```
-
-### Testing the Template
-
-Generate a test project locally:
-
-```bash
-cargo generate --path . --name test-project --define include_aide=true
-cd test-project
-cargo check
-cargo test
-```
-
-## Troubleshooting
-
-### "Failed to parse Cargo.toml"
-
-- Make sure template syntax is on separate lines in `.liquid` files
-- Cargo-generate needs `.liquid` extension for files with Jinja2 syntax
-
-### Missing Imports in Generated Code
-
-- Check that Rust edition is set to 2024 in `Cargo.toml.liquid`
-- Edition 2024 includes `Future` in the prelude
-
-### Conditional Features Not Working
-
-- Use `{% if variable %}...{% endif %}` syntax
-- Keep conditionals on their own lines in TOML files
-- Test with both `true` and `false` values
-
-## License
-
-Configure the license for your template as appropriate. The generated projects will inherit this license unless modified.
