+# CLI
+
+The BlueScript CLI (`bscript`) is the primary tool for managing projects, setting up board environments, and running code on your devices.
+
+## Installation
+
+```bash
+npm install -g @bscript/cli
+```
+
+## Project Management
+
+### `bscript project create`
+
+Creates a new BlueScript project with the necessary configuration files.
+
+```bash
+bscript project create <project-name> [options]
+```
+
+This command generates a new directory containing:
+*   `index.bs`: The main entry point for your application.
+*   `bsconfig.json`: The project configuration file.
+
+**Arguments:**
+*   `<project-name>`: The name of the directory to create.
+
+**Options:**
+
+| Option | Alias | Description |
+| :--- | :--- | :--- |
+| `--board` | `-b` | Specify the target board (e.g., `esp32`). If omitted, an interactive selection list will appear. |
+
+**Example:**
+```bash
+# Create a project interactively
+bscript project create my-app
+
+# Create a project specifically for ESP32
+bscript project create my-app --board esp32
+```
+
+---
+
+### `bscript project install`
+
+Installs project dependencies. This command has two modes:
+
+1. **Install All:** If run without arguments, it installs all dependencies listed in bsconfig.json.
+2. **Add Package:** If a Git URL is provided, it downloads the package, adds it to bsconfig.json, and installs it.
+
+```bash
+bscript project install [git-url] [options]
+```
+
+**Arguments:**
+*   `<git-url>`: (Optional) The URL of the Git repository to add as a dependency.
+
+**Options:**
+
+| Option | Alias | Description |
+| :--- | :--- | :--- |
+| `--tag` | `-t` | Specify a git tag or branch to checkout (e.g., `v1.0.0`, `main`). |
+
+**Example:**
+```bash
+# Restore all dependencies from bsconfig.json
+bscript project install
+
+# Install a specific library (e.g., GPIO library)
+bscript project install https://github.com/bluescript/gpio.git
+
+# Install a specific version of a library
+bscript project install https://github.com/bluescript/drivers.git --tag v2.0.0
+```
+
+---
+
+### `bscript project uninstall`
+
+Uninstall the specified package from the current project.
+
+```bash
+bscript project uninstall [package-name]
+```
+
+---
+
+### `bscript project run`
+
+Compiles the current project and executes it on a target device via Bluetooth.
+
+```bash
+bscript project run
+```
+
+When you run this command:
+1.  The CLI scans for available BlueScript devices over Bluetooth.
+2.  The project is compiled into native code on your host machine.
+3.  The code is transferred and executed immediately.
+
+---
+
+
+## Board Management
+
+These commands manage the toolchains and runtime environments for specific hardware platforms.
+
+### `bscript board setup`
+
+Downloads and installs the necessary environment files and dependencies for a specific board architecture.
+
+```bash
+bscript board setup <board-name>
+```
+
+**Arguments:**
+*   `<board-name>`: The target board identifier (e.g., `esp32`).
+
+---
+
+### `bscript board flash-runtime`
+
+Flashes the BlueScript Runtime firmware onto the microcontroller.
+**Note:** This command requires a physical USB connection to the device.
+
+```bash
+bscript board flash-runtime <board-name> [options]
+```
+
+**Arguments:**
+*   `<board-name>`: The target board identifier.
+
+**Options:**
+
+| Option | Alias | Description |
+| :--- | :--- | :--- |
+| `--port` | `-p` | Specify the serial port connected to the device (e.g., `COM3`, `/dev/ttyUSB0`). If omitted, the CLI will list available ports for selection. |
+
+**Example:**
+```bash
+bscript board flash-runtime esp32 --port /dev/ttyUSB0
+```
+
+---
+
+### `bscript board list`
+
+Lists all board architectures currently supported by the installed CLI version.
+
+```bash
+bscript board list
+```
+
+---
+
+### `bscript board remove`
+
+Removes the environment files and setup data for a specific board.
+
+```bash
+bscript board remove <board-name> [options]
+```
+
+By default, this command asks for confirmation before deleting files.
+
+**Options:**
+
+| Option | Alias | Description |
+| :--- | :--- | :--- |
+| `--force` | `-f` | Skips the confirmation prompt and forces removal. |
+
+---
+
+### `bscript board fullclean`
+
+Completely removes all configuration and environment files for **all** boards. This returns the CLI board configurations to a fresh state.
+
+```bash
+bscript board fullclean
+```
+By default, this command asks for confirmation before deleting files.
+
+**Options:**
+
+| Option | Alias | Description |
+| :--- | :--- | :--- |
+| `--force` | `-f` | Skips the confirmation prompt and forces removal. |
+
+---
+
+## Other Commands
+
+### `bscript repl`
+
+Starts an interactive Read-Eval-Print Loop (REPL) session with the target device.
+
+```bash
+bscript repl --board <board-name>
+```
+
+Unlike `bscript run` which compiles and sends the entire project, `bscript repl` utilizes the incremental compiler and shadow machine. It allows you to write code line-by-line, compiling only the differences and sending them to the device instantly via Bluetooth.
+
+
+**Options:**
+
+| Option | Alias | Description |
+| :--- | :--- | :--- |
+| `--board` | `-b` | Specify the target board (e.g., `esp32`). |
