-All the API <a href="https://docs.rs/teloxide/latest/teloxide/types/index.html">types</a> and <a href="https://docs.rs/teloxide/0.2.0/teloxide/requests/index.html">methods</a> are implemented with heavy use of <a href="https://en.wikipedia.org/wiki/Algebraic_data_type"><strong>ADT</strong>s</a> to enforce type safety and tight integration with IDEs. Bot&#39;s commands <a href="https://github.com/teloxide/teloxide#commands">have precise types too</a>, thereby serving as a self-documenting code and respecting the <a href="https://lexi-lambda.github.io/blog/2019/11/05/parse-don-t-validate/">parse, don&#39;t validate</a> programming idiom.
+All the API <a href="https://docs.rs/teloxide/latest/teloxide/types/index.html">types</a> and <a href="https://docs.rs/teloxide/latest/teloxide/requests/index.html">methods</a> are hand-written, with heavy use of <a href="https://en.wikipedia.org/wiki/Algebraic_data_type"><strong>ADT</strong>s</a> (algebraic data types) to enforce type safety and tight integration with IDEs. As few <code>Option</code>s as possible.

Dialogues management is independent of how/where they are stored: just replace one line and make them <a href="https://en.wikipedia.org/wiki/Persistence_(computer_science)">persistent</a> (for example, store on a disk, transmit through a network), without affecting the actual <a href="https://en.wikipedia.org/wiki/Finite-state_machine">FSM</a> algorithm. By default, teloxide stores all user dialogues in RAM. Default database implementations <a href="https://github.com/teloxide/teloxide/issues/183">are coming</a>!

+<h3 align="center">Strongly typed bot commands</h3>
+<p align="center">
+You can describe bot commands as enumerations, and then they'll be automatically constructed from strings. Just like you describe JSON structures in <a href="https://github.com/serde-rs/json">serde-json</a> and command-line arguments in <a href="https://github.com/TeXitoi/structopt">structopt</a>.

## Setting up your environment
1. [Download Rust](http://rustup.rs/).
2. Create a new bot using [@Botfather](https://t.me/botfather) to get a token in the format `123456789:blablabla`.
