+# Gurty - a CLI tool to setup your GURT Protocol server
+
+## Setup for Production
+
+For production deployments, you'll need to generate your own certificates since traditional Certificate Authorities don't support custom protocols:
+
+1. **Generate production certificates with OpenSSL:**
+   ```bash
+   # 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
+   ```
+
+2. **Deploy with production certificates:**
+   ```bash
+   cargo run --release serve --cert gurt-server.crt --key gurt-server.key --host 0.0.0.0 --port 4878
+   ```
+
+## Development Environment Setup
+
+To set up a development environment for GURT, follow these steps:
+1. **Install mkcert:**
+   ```bash
+   # Windows (with Chocolatey)
+   choco install mkcert
+   
+   # Or download from: https://github.com/FiloSottile/mkcert/releases
+   ```
+
+2. **Install local CA in system:**
+   ```bash
+   mkcert -install
+   ```
+   This installs a local CA in your **system certificate store**.
+
+3. **Generate localhost certificates:**
+   ```bash
+   cd gurted/protocol/cli
+   mkcert localhost 127.0.0.1 ::1
+   ```
+   This creates:
+   - `localhost+2.pem` (certificate)
+   - `localhost+2-key.pem` (private key)
+
+4. **Start GURT server with certificates:**
+   ```bash
+   cargo run --release serve --cert localhost+2.pem --key localhost+2-key.pem
+   ```
