-### Using a Module Independently
+## 💻 Using a Module Independently
 
 Each micro-repo is a standalone Zig package. To use any module independently:
 
-\`\`\`zig build.zig.zon\`\` — Clone and cache dependencies
-
-Example: Using zig-golden-float from any repo
-\`\`\`// build.zig.zon
+```zig
+// build.zig.zon
 .dependencies = .{
     .zig_golden_float = .{
         .url = "https://github.com/gHashTag/zig-golden-float/archive/refs/heads/main.tar.gz",
     },
 },
-\`\`
+```
+
+```bash
+zig fetch --save https://github.com/gHashTag/zig-golden-float/archive/refs/heads/main.tar.gz
+```
