## About
Textual adds interactivity to [Rich](https://github.com/Textualize/rich) with a Python API inspired by modern development development.
On modern terminal software (installed by default on most systems), Textual apps can use **16.7 million** colors with mouse support and smooth flicker-free animation. A powerful layout engine and re-usable components makes it possible to build apps that rival the desktop and web experience.
## Compatibility
Textual runs on Linux, macOS, and Windows. Textual requires Python 3.7 or above.
## Installing
Install Textual via pip:
```
pip install textual[dev]
```
The addition of `[dev]` installs Textual development tools.
## Reference commands
The `textual` command has a few sub-commands to preview Textual styles.
🎬 Easing reference
This is the *easing* reference which demonstrates the easing parameter on animation, with both movement and opacity. You can run it with the following command:
