 ```
+
+### Byte Array Conversion
+
+This library is based on two functions: `Hex.toHexString(Array[Byte])` and
+`Hex.fromHexString(String)`.
+
+```scala
+import gs.hex.v0.Hex
+
+val data: Array[Byte] = ???
+val encoded: String = Hex.toHexString(data)
+val decoded: Option[Array[Byte]] = Hex.fromHexString(encoded)
+```
+
+### Type Classes
+
+This library provides `HexEncode[A]` and `HexDecode[A]` for encoding and
+decoding arbitrary types as Hexadecimal strings. The types `Array[Byte]`,
+`String`, `Boolean`, `Int` and `Long` are supported by default.
+
+#### Example Type Class Implementations
+
+```scala
+given HexEncode[Array[Byte]] = new HexEncode[Array[Byte]] {
+  def toHexString(data: Array[Byte]): String = Hex.toHexString(data)
+}
+
+given HexDecode[Array[Byte]] = new HexDecode[Array[Byte]] {
+  def fromHexString(data: String): Option[Array[Byte]] =
+    Hex.fromHexString(data)
+}
+```
+
+#### Example Type Class Usage
+
+```scala
+def encode[A](data: A)(using HexEncode[A]): String =
+  data.toHex()
+
+def decode[A](data: String)(using HexDecode[A]): Option[A] =
+  data.fromHex()
