 This is a basic Swift implementation of Recursive Length Prefix Encoding, a serialisation method for encoding arbitrarily structured binary data (byte arrays).
 
 You can read more about it here:

-# Getting Started
-
-Encoding Strings and nested arrays of String
+# Interface
 
 ```swift
-// Encoding strings
-try! RLP.encode("dog") // \u{83}dog
+// Encoding Data
+RLP.encode(_ data: Data) -> Data
+
+// Encoding String
+RLP.encode(_ string: String, with encoding: String.Encoding = .ascii) throws -> Data
+
+// Encoding nested array of Data
+RLP.encode(nestedArrayOfData array: [Any]) throws -> Data
 
-// Encoding arrays is just as easy
-try! RLP.encode(["cat", "dog"]) // \u{c8}\u{83}cat\u{83}dog
+// Encoding nested array of String
+RLP.encode(nestedArrayOfString array: [Any], encodeStringsWith encoding: String.Encoding = .ascii) throws -> Data
 ```
