+ (description
+ "Yyjson is a high performance JSON library written in ANSI C. Some features include
+@itemize
+@item Fast: can read or write gigabytes per second JSON data on modern CPUs.
+@item Portable: complies with ANSI C (C89) for cross-platform compatibility.
+@item Strict: complies with RFC 8259 JSON standard, ensuring strict
+number format and UTF-8 validation.
+@item Extendable: offers options to allow comments, trailing commas, NaN/Inf,
+ and custom memory allocator.
+@item Accuracy: can accurately read and write int64, uint64, and double numbers.
+@item Flexible: supports unlimited JSON nesting levels, \u0000 characters,
+and non null-terminated strings.
+@item Manipulation: supports querying and modifying using JSON Pointer,
+JSON Patch and JSON Merge Patch.
+@item Developer-Friendly: easy integration with only one .h and one .c file.
