 //! Payphone is a Discord bot that allows users to make calls to each other, similar to a phone
 //! system.
-//! 
+//!
 //! # Setting Up
-//! 
+//!
 //! First of all, clone the Git repository and navigate to the project directory:
-//! 
+//!
 //! ```shell
 //! $ git clone --branch rewrite https://git.nyeki.dev/payphone/payphone.git
 //! $ cd payphone
 //! ```
-//! 
+//!
 //! To boot up Payphone, you'll need both a Discord bot token and  a Scylla database cluster with
 //! at least 3 nodes.
-//! 
+//!
 //! - To get a Discord bot token, create a new bot application on the
 //!   [Discord Developer Portal](https://discord.com/developers/applications).
-//! 
+//!
 //! - To set up a Scylla database cluster, make sure to have Docker and Docker Compose installed
 //!   and run `docker compose up -d`. A development cluster will be created with 3 nodes, with one
 //!   of them listening at `127.0.0.1:9042`.
-//! 
+//!
 //! To stop the database cluster at any time, run `docker compose down`. To stop it and delete the
 //! volumes (resetting the database), run `docker compose down -v`.
-//! 
+//!
 //! ## Booting Up
-//! 
+//!
 //! Payphone has a CLI interface that allows you to pass the bot token and database URL as CLI
 //! arguments. To get all possible arguments, run the following command:
-//! 
+//!
 //! ```shell
 //! $ cargo run -- --help
 //! ```
-//! 
+//!
 //! Payphone also supports configuration via environment variables and `.env` files by default.
-//! 
+//!
 //! ```env
 //! PAYPHONE_TOKEN="your_discord_bot_token"
 //! ```
-//! 
+//!
 //! All environment variables are prefixed with `PAYPHONE_` and can be used to override the CLI
 //! arguments.
-//! 
+//!
 //! # Framework
-//! 
+//!
 //! Payphone has a custom framework that allows you to create commands, components, and event
 //! handlers easily. The framework is designed to be modular and extensible, allowing you to add
 //! new features and commands without modifying the core codebase. The documentation for the
 //! framework is all in the [`framework`] module.
-//! 
+//!
 //! # Database
-//! 
+//!
 //! The database Payphone runs on is ScyllaDB, a high-performance NoSQL database compatible with
-//! Apache Cassandra. For documentation on how to interact with the database, check the 
+//! Apache Cassandra. For documentation on how to interact with the database, check the
 //! [`database`] module's documentation.
-//! 
+//!
 //! # Application Code
-//! 
+//!
 //! Payphone's application code is under the [`groups`] module. It contains all commands, events,
 //! embeds, and other configurations for the bot grouped in submodules (e.g. [`groups::calls`],
 //! [`groups::about`], etc.), all which can be found at the [`groups`] module's documentation.
-//! 
+//!
 //! Each submodule contains files like `commands.rs`, `events.rs`, `embeds.rs`, and `components.rs`
 //! that define the commands, events, embeds, and components for that group. Some common file names
 //! are:
-//! 
+//!
 //! - `commands.rs`: Contains the commands for the group.
 //! - `events.rs`: Contains the event handlers for the group.
 //! - `embeds.rs`: Contains the embeds for the group.
 //! - `components.rs`: Contains the components for the group (action rows, buttons, soon also
 //!   select menus).
-//! 
+//!
 //! Always try to follow the same structure and patterns as the existing code to maintain
 //! consistency and readability.
-//! 
+//!
 //! More documentation about each group can be found in the respective submodule's documentation.
