+OSUI is a powerful TUI library, what makes it special is it's design and features, it allows for both customization and easy of use.
+
+### Setup
+First, you need to install osui to a already existing [rust cargo](https://doc.rust-lang.org/cargo/getting-started/index.html) project, then in your project directory run:
+```bash
+cargo add osui
+```
+
+## Hello World App
+To make a hello world app in OSUI simply write this
+```rust src/main.rs
+use osui::Screen;
+
+fn main() -> std::io::Result<()> {
+    let mut screen = Screen::new();
+    
+    screen.draw(format!("Hello, World!"));
+
+    screen.run()
+}
+```
+
+## Hello World App With Velocity
+The text will move from left to right with a velocity of `100`
+```rust src/main.rs
+use osui::{Screen, extensions::velocity::{VelocityExtension, Velocity}};
+
+fn main() -> std::io::Result<()> {
+    let mut screen = Screen::new();
+    screen.extension(VelocityExtension);
+    
+    screen
+        .draw(format!("Hello, World!"))
+        .component(Velocity(100, 0)); // Velocity(x, y)
+
+    screen.run()
+}
+```
