 - **Network Diagnostics** — Interface stats, ping, traceroute, speed tests, routing table, DNS servers, connection analysis
 - **Report Generation** — Generate, save, and load comprehensive system health reports (`~/.server-pulse/reports/`)
+- **i18n** — Switch between English and Simplified Chinese at runtime (`L` / `Ctrl+L`); preference saved to `~/.server-pulse/config.json`

 ## Installation
 
-### Pre-built Binaries (Recommended)
-
-**curl:**
+### From source (this fork)
 
 ```bash
-curl -fsSL https://raw.githubusercontent.com/Server-Pulse/server-pulse/main/scripts/install.sh | bash
-```
-
-**wget:**
-
-```bash
-wget -qO- https://raw.githubusercontent.com/Server-Pulse/server-pulse/main/scripts/install.sh | bash
-```
-
-The install script auto-detects your platform, downloads the latest release, verifies the SHA256 checksum, and installs the binary to `/usr/local/bin/`.
-
-### Manual Download
-
-Download a specific release for Linux amd64:
-
-```bash
-sudo wget https://github.com/Server-Pulse/server-pulse/releases/download/vX.X.X/server-pulse-X.X.X-linux-amd64 -O /usr/local/bin/server-pulse
-sudo chmod +x /usr/local/bin/server-pulse
+git clone https://github.com/zhangyang-crazy-one/server-pulse.git
+cd server-pulse
+git checkout feat/chinese-ui
+make build
+sudo mv server-pulse /usr/local/bin/
 ```
 
-### From Source
-
-#### Prerequisites
-- Go 1.24+
-- Git
+Or:
 
 ```bash
-git clone https://github.com/Server-Pulse/server-pulse.git
-cd server-pulse
-make build
-sudo mv server-pulse /usr/local/bin/
+go build -o server-pulse .
+sudo install -m 755 server-pulse /usr/local/bin/server-pulse
 ```
