+CI/CD USAGE GUIDE
+=================
+
+AUTOMATIC TESTING
+-----------------
+Every push or PR automatically runs:
+  - Build on Ubuntu and macOS
+  - AddressSanitizer checks
+  - Valgrind memory leak detection
+
+Check status:
+  https://github.com/m1ngsama/TNT/actions
+
+
+CREATING RELEASES
+-----------------
+1. Update version in CHANGELOG.md
+
+2. Create and push tag:
+   git tag v1.0.0
+   git push origin v1.0.0
+
+3. GitHub Actions automatically:
+   - Builds binaries (Linux/macOS, AMD64/ARM64)
+   - Creates release
+   - Uploads binaries
+   - Generates checksums
+
+4. Release appears at:
+   https://github.com/m1ngsama/TNT/releases
+
+
+DEPLOYING TO SERVERS
+--------------------
+Single command on any server:
+  curl -sSL https://raw.githubusercontent.com/m1ngsama/TNT/main/install.sh | sh
+
+Or with specific version:
+  VERSION=v1.0.0 curl -sSL https://raw.githubusercontent.com/m1ngsama/TNT/main/install.sh | sh
+
+
+PRODUCTION SETUP (systemd)
+---------------------------
+1. Install binary (see above)
+
+2. Setup service:
+   sudo useradd -r -s /bin/false tnt
+   sudo mkdir -p /var/lib/tnt
+   sudo chown tnt:tnt /var/lib/tnt
+   sudo cp tnt.service /etc/systemd/system/
+   sudo systemctl daemon-reload
+   sudo systemctl enable --now tnt
+
+3. Check status:
+   sudo systemctl status tnt
+   sudo journalctl -u tnt -f
+
+
+UPDATING SERVERS
+----------------
+Stop service:
+  sudo systemctl stop tnt
+
+Run installer again:
+  curl -sSL https://raw.githubusercontent.com/m1ngsama/TNT/main/install.sh | sh
+
+Restart:
+  sudo systemctl start tnt
+
+
+PLATFORMS SUPPORTED
+-------------------
+✓ Linux AMD64 (x86_64)
+✓ Linux ARM64 (aarch64)
+✓ macOS Intel (x86_64)
+✓ macOS Apple Silicon (arm64)
