+# RLPSwift
+
+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:
+* [Ethereum Wiki - RLP](https://github.com/ethereum/wiki/wiki/RLP)
+* [Ethereum Yellowpaper](https://ethereum.github.io/yellowpaper/paper.pdf) (Appendix B)
+
+# Getting Started
+
+At the moment is possible to encode Strings and nested arrays of String
+
+```swift
+// Encoding strings
+RLP.encode("dog") // \u{83}dog
+
+// Encoding arrays is just as easy
+RLP.encode(["cat", "dog"]) // \u{c8}\u{83}cat\u{83}dog
+```
+
+# Installation
+
+### Manually
+This library is small, so you can easily install it manually by dragging and dropping RLP.swift inside your project
+
+# License
+
+RLPSwift is released under an [MIT](https://tldrlegal.com/license/mit-license) license. See [LICENSE](LICENSE) for more information.
