 Benvenuto! Welcome to Trallalelo Lang, the most whimsical and brain-tickling programming language inspired by the finest Italian-flavored brainrot.
 
-## Documentation
+## Getting Started
 
-(Coming soon)
+To run a Trallalelo program, you need to have Rust installed. Then, you can use the following command:
 
-## Ciao!
+```bash
+cargo run -- <file_name>.tralla
+```
+
+## Syntax
+
+A Trallalelo program must start with `Tralalero Tralala` and end with `Bombardiro Crocodilo`.
+
+## Keywords
+
+### `Tralalero Tralala`
+
+This is the entry point of the program. It must be the first line of your code.
+
+### `Bombardiro Crocodilo`
+
+This is the exit point of the program. It must be the last line of your code.
+
+### `Matteeeo bambini gusini "<message>"`
+
+This command prints a message to the console. The message must be enclosed in double quotes.
+
+## Ciao!
