+# TeamSpeak TUI Client
+
+A modern, fast, and lightweight TeamSpeak 3 client built in Go with a beautiful Terminal User Interface (TUI).
+
+## 🚀 Features
+- **Low Latency Audio**: Optimized for both Windows (WASAPI) and Linux (PortAudio).
+- **Responsive UI**: Built with Bubble Tea for a smooth terminal experience.
+- **Cross-Platform**: Full support for Windows and Linux (including WSL2).
+- **Audio Controls**: Per-user volume and mute indicators.
+
+## 🛠️ Linux Dependencies
+
+To build the project on Linux (including Ubuntu/WSL2), you need to install the following system libraries:
+
+```bash
+sudo apt-get update
+sudo apt-get install -y \
+    libportaudio2 \
+    portaudio19-dev \
+    libopus-dev \
+    libpulse-dev
+```
+
+### 🔊 WSL2 Audio Setup
+
+WSL2 does not have direct access to your Windows audio hardware. To enable audio, we recommend using a PulseAudio network bridge:
+
+1. **Install PulseAudio on Windows** (e.g., via [portable binaries](https://www.freedesktop.org/wiki/Software/PulseAudio/Ports/Windows/)).
+2. **Enable TCP**: Edit `default.pa` in PulseAudio and add:
+   `load-module module-native-protocol-tcp auth-anonymous=1 listen=0.0.0.0`
+3. **Environment Variable**: Set the `PULSE_SERVER` in your WSL2 shell:
+   ```bash
+   export PULSE_SERVER=tcp:$(grep nameserver /etc/resolv.conf | awk '{print $2}'):4713
+   ```
+
+## 🏗️ Building
+
+```bash
+# General build
+go build -o ts-tui ./cmd/tui
+
+# Run with debug logging (highly recommended for audio setup)
+go run ./cmd/tui --server your-ip:9987 --debug
+```
+
+## ⌨️ Common Keys

+## 💻 Development with VS Code
+
+This project uses Go **build tags** to support multiple platforms from the same codebase. This can sometimes cause "redeclared" errors or "undefined" symbols in VS Code if not configured correctly.
+
+### Recommended Setup
+
+1. **Windows + MSYS2**: If you are developing on Windows and have Opus/PortAudio installed via MSYS2, your `.vscode/settings.json` should include the paths to your MinGW64 environment:
+   ```json
+   {
+       "go.toolsEnvVars": {
+           "CGO_ENABLED": "1",
+           "PATH": "C:\\msys64\\mingw64\\bin;${env:PATH}",
+           "PKG_CONFIG_PATH": "C:\\msys64\\mingw64\\lib\\pkgconfig"
+       }
+   }
+   ```
+2. **Build Tags**: Do **not** force both tags simultaneously (e.g., `-tags=linux,windows`) as this will cause "redeclared" errors for types defined in both systems (like `Player` or `Capturer`).
+3. **Switching OS Analysis**: If you are on Windows but want to check for errors in the Linux files, update your settings to:
+   ```json
+   "go.toolsEnvVars": { "GOOS": "linux" }
+   ```
+
+### Pro Tip: VS Code Remote - WSL
+For the best experience when working on Linux features from Windows, use the **WSL extension**. Open VS Code inside your WSL environment (`code .` from the WSL terminal). This allows `gopls` to run directly in Linux, where all system headers and libraries are natively available.
+
+## 🤖 Gitea Actions (CI/CD)
+
+El archivo `.gitea/workflows/build.yml` automatiza la compilación y la creación de Releases.
+
+1. **Builds automáticas**: Cada `push` a `master` genera artefactos descargables.
+2. **Releases automáticas**: Al subir un tag (`git tag v*`), se crea una Release con:
+   - `ts3-tui-windows-x86_64.zip` (Portable: exe + dlls).
+   - `ts3-tui-linux-x86_64` (Para PC/WSL2).
+   - `ts3-tui-linux-aarch64` (Para ARM/Raspberry Pi).
+
+### Cómo usar tu propio Windows como Runner
+
+Si tu Gitea no tiene runners públicos, puedes convertir tu propia máquina Windows en uno:
+
+1. **Descarga `act_runner`**: Descarga el binario oficial de [Gitea Actions Runner](https://gitea.com/gitea/act_runner/releases).
+2. **Registro**:
+   - Ve a tu instancia de Gitea -> Administración del Sitio -> Actions -> Runners.
+   - Copia el **Registration Token**.
+   - Ejecuta: `./act_runner register`
+   - Introduce la URL de tu Gitea y el token.
+   - En **labels**, asegúrate de poner `windows-latest:host`.
+3. **Ejecución**:
+   - Lanza el runner: `./act_runner daemon`.
+   - Ahora, cualquier push lanzará la build en tu PC de forma automática.
+
+> [!TIP]
+> El workflow usa **MSYS2** automáticamente para instalar `opus` y `portaudio` en el entorno temporal de la build, así que no necesitas configurar nada extra en el sistema del runner.
+
+### Cómo añadir un Runner en WSL2 (para x86_64)
+
+Si tu runner principal es ARM (como una Raspberry Pi) y quieres compilar para tu PC (x86_64), lo mejor es poner un runner dentro de WSL2:
+
+1. **Entra en WSL2**: Ejecuta `wsl` en tu terminal.
+2. **Descarga `act_runner`**:
+   ```bash
+   curl -L https://gitea.com/gitea/act_runner/releases/download/v0.2.13/act_runner-0.2.13-linux-amd64 -o act_runner
+   chmod +x act_runner
+   ```
+3. **Registro**:
+   - Igual que en Windows, usa `./act_runner register` con el token de tu Gitea.
+   - En **labels**, pon algo como `linux-x86_64:host`.
+4. **Actualiza el workflow**:
+   - En `.gitea/workflows/build.yml`, cambia `runs-on: ubuntu-latest` por `runs-on: linux-x86_64` en el job `build-linux`.
+
+> [!NOTE]
+> Al usar el label `:host`, el runner usará las herramientas instaladas en tu Linux de WSL2 sin necesidad de Docker, lo que lo hace mucho más rápido.
