+Just enter the directory (for example, `cd dialogue_bot`) and execute `cargo run` to run an example. Don't forget to initialise the `TELOXIDE_TOKEN` environmental variable.
+
+  - [ping_pong_bot](ping_pong_bot) - Answers "pong" to each incoming message.
+  - [simple_commands_bot](simple_commands_bot) - Shows how to deal with bot's commands.
+  - [guess_a_number_bot](guess_a_number_bot) - The "guess a number" game.
+  - [dialogue_bot](dialogue_bot) - Drive a dialogue with a user using a type-safe finite automaton.
+  - [admin_bot](admin_bot) - A bot, which can ban, kick, and mute on a command.
+  - [multiple_handlers_bot](multiple_handlers_bot) - Shows how multiple dispatcher's handlers relate to each other.

-//! Dispatching updates from chats.

-//! There are four main components:

-//!  1. Your session type `Session`, which designates a dialogue state at the
-//! current moment.
-//!  2. [`Storage`] that encapsulates all the sessions.
-//!  3. Your handler of type `H: async Fn(Session, Update) ->
-//! HandleResult<Session>` that receives an update and turns your session into
-//! the next state.
-//!  4. [`Dispatcher`], which encapsulates your handler and [`Storage`], and has
-//! the [`dispatch(Update) -> DispatchResult`] function.
-//!
-//! Every time you call [`.dispatch(update)`] on your dispatcher, the following
-//! steps are executed:
-//!
-//!  1. If a supplied update is not from a chat, return
-//! [`DispatchResult::Unhandled`].
-//!  2. If a storage doesn't contain a session from this chat, supply
-//! `Session::default()` into you handler, otherwise, supply the previous
-//! session.
-//!  3. If a handler has returned [`SessionState::Terminate`], remove the
-//! session from a storage, otherwise force the storage to update the session.

+//!  1. Your type `D`, which designates a dialogue state at the current

+//!  2. [`Storage`], which encapsulates all the dialogues.
+//!  3. Your handler, which receives an update and turns your dialogue into the
+//! next state.
+//!  4. [`DialogueDispatcher`], which encapsulates your handler, [`Storage`],
+//! and implements [`CtxHandler`].

+//! You supply [`DialogueDispatcher`] into [`Dispatcher`]. Every time

+//! steps are executed:
+//!
+//!  1. If a storage doesn't contain a dialogue from this chat, supply
+//! `D::default()` into you handler, otherwise, supply the saved session
+//! from this chat.
+//!  2. If a handler has returned [`DialogueStage::Exit`], remove the session
+//! from the storage, otherwise ([`DialogueStage::Next`]) force the storage to
+//! update the session.
+//!
+//! Please, see [examples/dialogue_bot] as an example.

-//! Update dispatching.
+//! Updates dispatching.
+//!
+//! The key type here is [`Dispatcher`]. It encapsulates [`Bot`], handlers for
+//! [11 update kinds] (+ for [`Update`]) and [`ErrorHandler`] for them. When
+//! [`Update`] is received from Telegram, the following steps are executed:
+//!
+//!  1. It is supplied into an appropriate handler (the first ones is those who
+//! accept [`Update`]).
+//!  2. If a handler failed, invoke [`ErrorHandler`] with the corresponding
+//! error.
+//!  3. If a handler has returned [`DispatcherHandlerResult`] with `None`,
+//! terminate the pipeline, otherwise supply an update into the next handler
+//! (back to step 1).
+//!
+//! The pipeline is executed until either all the registered handlers were
+//! executed, or one of handlers has terminated the pipeline. That's simple!
+//!
+//!  1. Note that handlers implement [`CtxHandler`], which means that you are
+//! able to supply [`DialogueDispatcher`] as a handler, since it implements
+//! [`CtxHandler`] too!
+//!  2. Note that you don't always need to return [`DispatcherHandlerResult`]
+//! explicitly, because of automatic conversions. Just return `Result<(), E>` if
+//! you want to terminate the pipeline (see the example below).

+//! A full-featured framework that empowers you to easily build [Telegram bots]
+//! using the [`async`/`.await`] syntax in [Rust]. It handles all the difficult
+//! stuff so you can focus only on your business logic.
+//!
+//! ## Features
+//!  - **Type-safe.** teloxide leverages the Rust's type system with two serious
+//!    implications: resistance to human mistakes and tight integration with
+//!    IDEs. Write fast, avoid debugging as possible.
+//!
+//!  - **Persistency.** By default, teloxide stores all user dialogues in RAM,
+//!    but you can store them somewhere else (for example, in DB) just by
+//!    implementing 2 functions.
+//!
+//!  - **Convenient dialogues system.** Define a type-safe [finite automaton]
+//!    and transition functions to drive a user dialogue with ease (see the
+//! examples below).
+//!
+//!  - **Convenient API.** Automatic conversions are used to avoid boilerplate.
+//!    For example, functions accept `Into<String>`, rather than `&str` or
+//!    `String`, so you can call them without `.to_string()`/`.as_str()`/etc.
+//!
+//! ## Getting started
+//!  1. Create a new bot using [@Botfather] to get a token in the format
+//! `123456789:blablabla`.  2. Initialise the `TELOXIDE_TOKEN` environmental
+//! variable to your token:
+//! ```bash
+//! # Unix
+//! $ export TELOXIDE_TOKEN=MyAwesomeToken
+//!
+//! # Windows
+//! $ set TELOXITE_TOKEN=MyAwesomeToken
+//! ```
+//!  3. Be sure that you are up to date:
+//! ```bash
+//! $ rustup update stable
+//! ```
+//!
+//!  4. Execute `cargo new my_bot`, enter the directory and put these lines into
+//! your `Cargo.toml`:
+//! ```toml
+//! [dependencies]
+//! teloxide = "0.1.0"
+//! log = "0.4.8"
+//! tokio = "0.2.11"
+//! pretty_env_logger = "0.4.0"
+//! ```
+//!
+//! ## The ping-pong bot
+//! This bot has a single message handler, which answers "pong" to each incoming
+//!  message:
+//!
+//! ([Full](https://github.com/teloxide/teloxide/blob/dev/examples/ping_pong_bot/src/main.rs))
+//! ```rust,no_run
+//! use teloxide::prelude::*;
+//!
+//! # #[tokio::main]
+//! # async fn main() {
+//! teloxide::enable_logging!();
+//! log::info!("Starting the ping-pong bot!");
+//!
+//! let bot = Bot::from_env();

+//!         Ok(())
+//!     })
+//!     .dispatch()
+//!     .await;
+//! # }
+//! ```
+//!
+//! ## Commands
+//! Commands are defined similar to how we define CLI using [structopt]. This
+//! bot says "I am a cat! Meow!" on `/meow`, generates a random number within
+//! [0; 1) on `/generate`, and shows the usage guide on `/help`:
+//!
+//! ([Full](https://github.com/teloxide/teloxide/blob/dev/examples/simple_commands_bot/src/main.rs))

+//! Our [finite automaton], designating a user dialogue, cannot be in an invalid
+//! state. See [examples/dialogue_bot] to see a bit more complicated bot with
+//! dialogues.
+//!
+//! [See more examples](https://github.com/teloxide/teloxide/tree/dev/examples).
+//!
+//! ## Recommendations
+//!
+//!  - Use this pattern:
+//!
+//!  ```rust
+//!  #[tokio::main]
+//!  async fn main() {
+//!      run().await;
+//!  }
+//!
+//!  async fn run() {
+//!      // Your logic here...
+//!  }
+//!  ```
+//!
+//!  Instead of this:
+//!
+//!  ```rust
+//! #[tokio::main]
+//!  async fn main() {
+//!      // Your logic here...
+//!  }
+//!  ```
+//!
+//!  The second one produces very strange compiler messages because of the
+//! `#[tokio::main]` macro. However, the examples above use the second one for
+//! brevity.
