+#             [2] https://zsh.sourceforge.io/Doc/Release/Files.html#index-ZDOTDIR_002c-use-of
+#   ZSH     - path to the Oh My Zsh repository folder (default: $HOME/.oh-my-zsh)
+#   REPO    - name of the GitHub repo to install from (default: ohmyzsh/ohmyzsh)
+#   REMOTE  - full remote URL of the git repo to install (default: GitHub via HTTPS)
+#   BRANCH  - branch to check out immediately after install (default: master)
+#
+# Other options:
+#   CHSH                   - 'no' means the installer will not change the default shell (default: yes)
+#   RUNZSH                 - 'no' means the installer will not run zsh after the install (default: yes)
+#   KEEP_ZSHRC             - 'yes' means the installer will not replace an existing .zshrc (default: no)
+#   OVERWRITE_CONFIRMATION - 'no' means the installer will not ask for confirmation to overwrite the existing .zshrc (default: yes)
+#
+# You can also pass some arguments to the install script to set some these options:

+#   --unattended: sets both CHSH and RUNZSH to 'no'
+#   --keep-zshrc: sets KEEP_ZSHRC to 'yes'

+///
+/// This module provides all HTTP communication between WatcherAgent and the backend server.
+///
+/// ## Responsibilities
+/// - **Registration:** Registers the agent with the backend and retrieves its server ID and IP address.
+/// - **Heartbeat:** Periodically sends heartbeat signals to indicate liveness.
+/// - **Metrics Reporting:** Sends collected hardware and network metrics to the backend.
+/// - **Command Listening:** Polls for and executes remote commands from the backend (e.g., update image, restart container).
+///
+/// ## Usage
+/// These functions are called from the main agent loop and background tasks. All network operations are asynchronous and robust to transient failures.

-/// WatcherAgent - A Rust-based system monitoring agent
-/// This agent collects hardware metrics and sends them to a backend server.
-/// It supports CPU, GPU, RAM, disk, and network metrics.
+/// # WatcherAgent
+///
+/// **WatcherAgent** is a cross-platform system monitoring agent written in Rust.
+///
+/// ## Overview
+/// This agent collects real-time hardware metrics (CPU, GPU, RAM, disk, network) and communicates with a backend server for registration, reporting, and remote control. It is designed for deployment in environments where automated monitoring and remote management of system resources is required.
+///
+/// ## Features
+/// - **Hardware Metrics:** Collects CPU, GPU, RAM, disk, and network statistics using platform-specific APIs.
+/// - **Docker Integration:** Detects and manages its own Docker container, supports image updates and container restarts.
+/// - **Server Communication:** Registers with a backend server, sends periodic heartbeats, and reports metrics securely.
+/// - **Remote Commands:** Listens for and executes commands from the backend (e.g., update image, restart container, stop agent).
+///
+/// ## Modules
+/// - [`api`]: Handles HTTP communication with the backend server (registration, heartbeat, metrics, commands).
+/// - [`hardware`]: Collects hardware metrics from the host system (CPU, GPU, RAM, disk, network).
+/// - [`metrics`]: Orchestrates metric collection and reporting.
+/// - [`models`]: Defines data structures for server communication and metrics.
+/// - [`docker`]: Integrates with Docker for container management and agent lifecycle.
+///
+/// ## Usage
+/// Run the agent with the backend server URL as an argument:
+/// ```sh
+/// watcheragent <server-url>
+/// ```
+///
+/// The agent will register itself, start collecting metrics, and listen for remote commands.
