 2. **Import and Use:**
    After building and installing, you can import `chroma` into your Zig code:
 
-   ```zig
-   const std = @import("std");
-   const chroma = @import("lib.zig");
+```zig
+const std = @import("std");
+const chroma = @import("lib.zig");
+
+pub fn main() !void {
+    const examples = [_]struct { fmt: []const u8, arg: ?[]const u8 }{
+        // Basic color and style
+        .{ .fmt = "{bold,red}Bold and Red{reset}", .arg = null },
+        // Combining background and foreground with styles
+        .{ .fmt = "{fg:cyan,bg:magenta}{underline}Cyan on Magenta underline{reset}", .arg = null },
+        // Nested styles and colors
+        .{ .fmt = "{green}Green {bold}and Bold{reset,blue,italic} to blue italic{reset}", .arg = null },
+        // Extended ANSI color with arg example
+        .{ .fmt = "{bg:120}Extended ANSI {s}{reset}", .arg = "Background" },
+        // True color specification
+        .{ .fmt = "{fg:255;100;0}True Color Orange Text{reset}", .arg = null },
+        // Mixed color and style formats
+        .{ .fmt = "{bg:28,italic}{fg:231}Mixed Background and Italic{reset}", .arg = null },
+        // Unsupported/Invalid color code >= 256, Error thrown at compile time
+        // .{ .fmt = "{fg:999}This should not crash{reset}", .arg = null },
+        // Demonstrating blink, note: may not be supported in all terminals
+        .{ .fmt = "{blink}Blinking Text (if supported){reset}", .arg = null },
+        // Using dim and reverse video
+        .{ .fmt = "{dim,reverse}Dim and Reversed{reset}", .arg = null },
+        // Custom message with dynamic content
+        .{ .fmt = "{blue,bg:magenta}User {bold}{s}{reset,0;255;0} logged in successfully.", .arg = "Charlie" },
+        // Combining multiple styles and reset
+        .{ .fmt = "{underline,cyan}Underlined Cyan{reset} then normal", .arg = null },

+        // Jujutsu Kaisen !!
+        .{ .fmt = "{bg:72,bold,italic}Jujutsu Kaisen !!{reset}", .arg = null },
+    };
+
+    inline for (examples) |example| {
+        if (example.arg) |arg| {
+            std.debug.print(chroma.format(example.fmt) ++ "\n", .{arg});
+        } else {
+            std.debug.print(chroma.format(example.fmt) ++ "\n", .{});
+        }
+    }
+
+    std.debug.print(chroma.format("{blue}{underline}Eventually{reset}, the {red}formatting{reset} looks like {130;43;122}{s}!\n"), .{"this"});
