+# JA4T Fingerprint Parser
+
+This Go package provides a parser for the JA4T (Joint Application Protocol Handler) fingerprint. The parser can read PCAP files and extract JA4T fingerprints from TCP packets.
+
+
+## Features
+
+- Reads PCAP files using the pcap library
+- Parses TCP packets to extract JA4T fingerprints
+- Supports parsing of multiple JA4T fingerprints in a single file
+
+## Usage
+
+To use this package, simply import it into your Go program and call the ParseFile function:
+
+```
+package main
+
+import (
+	"fmt"
+	"ja4t"
+)
+
+func main() {
+	files, err := ja4t.ParseFile("example.pcap")
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	for _, file := range files {
+		fmt.Println(file.String())
+	}
+}
+```
