 # Quick Start
 
-To set up the environment, please check out the [tutorial video](https://youtu.be/g5Npb6DsO-0) or the steps below.
+Check out the [tutorial video](https://youtu.be/g5Npb6DsO-0) or follow these steps.

-* Raspberry Pi (Zero 2W/3B/3B+/4B/5).
-* CSI or USB Camera Module.
-
-## Environment Setup
+- Raspberry Pi Zero 2W, 3B, 4B, or 5
+- CSI or USB camera (supports libcamera or V4L2)
 
-### 1. Install Raspberry Pi OS
+## Setup
 
-Use the [Raspberry Pi Imager](https://www.raspberrypi.com/software/) to install Raspberry Pi Lite OS on your microSD card.
+### 1. Flash Raspberry Pi OS
 
-<details>
-  <summary>
-    <b>💡 Can I use a regular Raspberry Pi OS, or does it have to be Lite?</b>
-  </summary>
-
-> You can use either the Lite or full Raspberry Pi OS (the official recommended versions), but Lite OS is generally more efficient.
-
-</details>
+Use [Raspberry Pi Imager](https://www.raspberrypi.com/software/) to flash **Lite OS** (or full OS) to SD card.
 
 ### 2. Install Dependencies
 
 ```bash
 sudo apt update
-sudo apt install libcamera0.5 libmosquitto1 pulseaudio libavformat59 libswscale6
+sudo apt isnstall libcamera0.5 libmosquitto1 pulseaudio libavformat59 libswscale6
 ```

+### 3. Download App
 
-Prepare the binary file from [Releases](https://github.com/TzuHuanTai/RaspberryPi-WebRTC/releases).
+Get the latest [release binary](https://github.com/TzuHuanTai/RaspberryPi-WebRTC/releases) .
 ```bash
-wget https://github.com/TzuHuanTai/RaspberryPi-WebRTC/releases/latest/download/pi-webrtc-v1.0.7_raspios-bookworm-arm64.tar.gz

+tar -xzf pi-webrtc-v1.1.0_raspios-bookworm-arm64.tar.gz
 ```
 
-### 4. Set Up MQTT
-
-You can use a free cloud MQTT service like  [HiveMQ](https://www.hivemq.com) or [EMQX](https://www.emqx.com/en), or set up your own self-hosted broker.

-    <b>💡 Is MQTT registration necessary, and why is MQTT needed?</b>
-  </summary>
+### 4. MQTT Signaling
 
-> MQTT is one option for signaling P2P connection information between your camera and the client UI. WHEP, on the other hand, runs an HTTP service locally and does not require a third-party server. It is only suitable for devices with a public hostname. If you choose to self-host an MQTT server (e.g., [Mosquitto](doc/SETUP_MOSQUITTO.md)) and need to access the signaling server remotely via mobile data, you may need to set up DDNS, port forwarding, and SSL/TLS.
+Use [HiveMQ](https://www.hivemq.com), [EMQX](https://www.emqx.com/en), or a [self-hosted](doc/SETUP_MOSQUITTO.md) broker.
 
-</details>
+> [!TIP]
+> **MQTT** lets your Pi camera and client exchange WebRTC connection info.
+**WHEP** doesn’t need a broker but requires a public hostname.
