+# FIGlet Font Examples
+
+The `figlet-rs` crate supports multiple fonts. Here are some examples of how to use different fonts:
+
+## Using Different Fonts
+
+```rust
+use figlet_rs::FIGfont;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Standard font (built-in)
+    let standard = FIGfont::standard()?;
+    if let Some(fig) = standard.convert("Standard") {
+        println!("{}", fig);
+    }
+    
+    // You can also load custom fonts from files
+    // Download fonts from: http://www.figlet.org/fontdb.cgi
+    
+    // Example with a custom font file:
+    // let font = FIGfont::from_file("path/to/font.flf")?;
+    // if let Some(fig) = font.convert("Custom") {
+    //     println!("{}", fig);
+    // }
+    
+    Ok(())
+}
+```
+
+## Popular FIGlet Fonts
+
+Some popular fonts you might want to try (download from figlet.org):
+
+- **standard** - The default, classic font (built-in)
+- **banner** - Large block letters (similar to the Unix `banner` command)
+- **big** - Large letters
+- **block** - Blocky style
+- **bubble** - Rounded bubble letters
+- **digital** - Digital/LED style
+- **lean** - Slanted letters
+- **mini** - Compact font
+- **script** - Cursive style
+- **shadow** - Letters with shadows
+- **slant** - Slanted text
+- **small** - Small letters
+
+## Example Output (Standard Font)
+
+```
+  _   _      _ _       
+ | | | | ___| | | ___  
+ | |_| |/ _ \ | |/ _ \ 
+ |  _  |  __/ | | (_) |
+ |_| |_|\___|_|_|\___/ 
+```
+
+## Adding Custom Fonts to Your Project
+
+1. Download fonts from http://www.figlet.org/fontdb.cgi
+2. Place `.flf` files in a `fonts/` directory in your project
+3. Load them with `FIGfont::from_file("fonts/yourfont.flf")`
+4. If using Nix, include the font files in your Docker image
+
+## Alternative: Multiple Text Styles
+
+You can also create multiple banner styles in your application:
+
+```rust
+fn print_banner(text: &str) {
+    let font = FIGfont::standard().unwrap();
+    if let Some(figure) = font.convert(text) {
+        println!("{}", figure);
+    }
+}
+
+fn main() {
+    print_banner("HELLO");
+    print_banner("WORLD");
+}
+```
