+more.
+
+The main features include:
+
+@itemize
+@item Written in clean and efficient C++11, built for speed
+@item Ultra fast with new match algorithms beating grep, ripgrep, silver
+      searcher, hyperscan, etc.
+@item Multi-threaded search using high-performance lock-free job queue stealing
+@item Multi-threaded task-parallel decompression and search
+@item Optimized pattern matching (AVX, SSE2, ARM NEON/AArch64)
+@item Optimized asynchronous IO for efficient concurrent searching
+@item Thoroughly tested (includes over 1000 test cases)
+@item Compatible with the standard GNU/BSD grep command-line options
+@item Comprehensive how-to tutorial for beginners to advanced users
+@item Interactive query UI to enter search patterns
+@item Select files to search by file types, filename suffix, and \"magic bytes\"
+@item Search archives (cpio, jar, tar, pax, zip)
+@item Search compressed files (zip, gz, Z, bz, bz2, lzma, xz)
+@item Search pdf, doc, docx, xls, xlxs, and more using filters
+@item Search binary files and display hexdumps with binary pattern matches
+@item Search UTF-encoded files with Unicode pattern matches (by default)
+@item Search files encoded in ISO-8859-1 thru 16, CP 437, CP 850, MAC, KOI8, etc.
+@item Search files excluding files specified by .gitignore etc.
+@item Search patterns across newlines, matching multiple lines at once
+@item Search patterns excluding negative patterns (\"match this but not that\")
+@item Includes predefined regex patterns to search source code, XML, JSON, HTML
+@item Output results in CSV, JSON, XML, and user-specified formats
+@item Sort matching files by name, size, and time
+@end itemize")
