Gurty uses a TOML configuration file to manage server settings. The gurty.template.toml file provides a complete configuration template with all available options:

Sections

Server: Basic server settings (host, port, protocol version, connection limits)
TLS: Certificate and private key configuration for secure connections
Logging: Logging levels, request/response logging, and log file paths
Security: File access restrictions, allowed HTTP methods, and rate limiting
Error Pages: Custom error page templates and default error responses
Headers: Custom HTTP headers for security and server identification

Using Configuration Files

Copy the configuration template:
```
cp gurty.template.toml gurty.toml
```
Edit the configuration to match your environment. (optional)
Use the configuration file:
```
gurty serve --config gurty.toml
```

Setup for Production

For production deployments, you'll need to generate your own certificates since traditional Certificate Authorities don't support custom protocols:

Generate production certificates with OpenSSL:

# Generate private key
openssl genpkey -algorithm RSA -out gurt-server.key -pkcs8 -v

# Generate certificate signing request
openssl req -new -key gurt-server.key -out gurt-server.csr

# Generate self-signed certificate (valid for 365 days)
openssl x509 -req -days 365 -in gurt-server.csr -signkey gurt-server.key -out gurt-server.crt

# Or generate both key and certificate in one step
openssl req -x509 -newkey rsa:4096 -keyout gurt-server.key -out gurt-server.crt -days 365 -nodes

Copy the configuration template and customize:
```
cp gurty.template.toml gurty.toml
```

Deploy with production certificates and configuration:

gurty serve --config gurty.toml

Or specify certificates explicitly:

gurty serve --cert gurt-server.crt --key gurt-server.key --config gurty.toml

Development Environment Setup

To set up a development environment for GURT, follow these steps:

Install mkcert:

# Windows (with Chocolatey)
choco install mkcert

# Or download from: https://github.com/FiloSottile/mkcert/releases

Install local CA in system:
```
mkcert -install
```
This installs a local CA in your system certificate store.
Generate localhost certificates:
```
cd gurted/protocol/cli
mkcert localhost 127.0.0.1 ::1
```
This creates:
- localhost+2.pem (certificate)
- localhost+2-key.pem (private key)
Copy the configuration template and customize:
```
cp gurty.template.toml gurty.toml
```

Start GURT server with certificates and configuration:

gurty serve --config gurty.toml

Or specify certificates explicitly:

gurty serve --cert localhost+2.pem --key localhost+2-key.pem --config gurty.toml
