+# seme - Second-Me CLI Tool
+
+`seme` is a command-line tool written in Golang to manage the lifecycle of Second-Me application services. It replaces the original set of shell scripts with a more consistent interface and better error handling.
+
+## Installation
+
+### Building from Source
+
+```bash
+git clone https://github.com/bitliu/Second-Me.git
+cd Second-Me/seme
+go build -o seme
+```
+
+You can then move the compiled binary to a directory in your system path, for example:
+
+```bash
+sudo mv seme /usr/local/bin/
+```
+
+## Usage
+
+`seme` provides the following commands:
+
+### Setting Up the Environment
+
+```bash
+# Set up the complete environment (Python, llama.cpp, and frontend)
+seme setup
+
+# Set up specific components only
+seme setup python
+seme setup llama
+seme setup frontend
+
+# Skip confirmation steps
+seme setup --skip-confirmation
+```
+
+### Starting Services
+
+```bash
+# Start all services (frontend and backend)
+seme start
+
+# Start backend service only
+seme start --backend-only
+```
+
+### Stopping Services
+
+```bash
+# Stop all services
+seme stop
+```
+
+### Restarting Services
+
+```bash
+# Restart all services
+seme restart
+
+# Restart backend service only
+seme restart --backend-only
+
+# Force restart (terminate all related processes)
+seme restart --force
+```
+
+### Checking Service Status
+
+```bash
+# Check the status of all services
+seme status
+```
+
+## Configuration
+
+`seme` will search for a `.env` file in the current directory and its parent directories to load environment variables. You can also specify the location of the environment variable file using command-line arguments:
+
+```bash
+seme --env-file /path/to/.env start
+```
+
+You can also specify the project root directory:
+
+```bash
+seme --base-path /path/to/project start
+```
+
+## Global Options
+
+The following options are available for all commands:
+
+- `--base-path string`: Specify the project root directory
+- `--env-file string`: Specify the path to the environment variable file
+- `-v, --verbose`: Enable verbose output mode
+- `-h, --help`: Show help information
+
+## Shell Completion
+
+`seme` supports generating shell completion scripts for different shells:
+
+```bash
+# Generate bash completion script
+seme completion bash > ~/.bash_completion.d/seme
+
+# Generate zsh completion script
+seme completion zsh > "${fpath[1]}/_seme"
+
+# Generate fish completion script
+seme completion fish > ~/.config/fish/completions/seme.fish
+```
