Bubble Tea programs are comprised of a **model** that describes the application Bubble Tea programs are comprised of a **model** that describes the application
state and three simple functions that are centered around that model: state and three simple methods on that model:

* **Update**, a function that handles incoming events and updates the model accordingly. * **Update**, a function that handles incoming events and updates the model accordingly.

## What's Next?
This tutorial covers the basics of building an interactive terminal UI, but
in the real world you'll also need to perform I/O. To learn about that have a
look at the [Command Tutorial][cmd]. It's pretty simple.
There are also several [Bubble Tea examples][examples] available and, of course,
there are [Go Docs][docs].

### Bubble Tea in the Wild
For some Bubble Tea programs in production, see:
* [Glow](https://github.com/charmbracelet/glow): a markdown reader, browser and online markdown stash
* [The Charm Tool](https://github.com/charmbracelet/charm): the Charm user account manager
### Libraries we use with Bubble Tea
* [Bubbles][bubbles] various Bubble Tea components
* [Termenv][termenv]: Advanced ANSI styling for terminal applications
* [Reflow][reflow]: ANSI-aware methods for reflowing blocks of text
* [go-runewidth][runewidth]: Measure the physical width of strings in terms of terminal cells. Many runes, such as East Asian charcters and emojis, are two cells wide, so measuring a layout with `len()` often won't cut it.
