+## API
 
 `rlp.encode(plain)` - RLP encodes an `Array`, `Buffer` or `String` and returns a `Buffer`.
 
 `rlp.decode(encoded, [skipRemainderCheck=false])` - Decodes an RLP encoded `Buffer`, `Array` or `String` and returns a `Buffer` or an `Array` of `Buffers`. If `skipRemainderCheck` is enabled, `rlp` will just decode the first rlp sequence in the buffer. By default, it would throw an error if there are more bytes in Buffer than used by rlp sequence.
