-The purpose of RLP (Recursive Linear Prefix) qis to encode arbitrarily
+The purpose of RLP (Recursive Linear Prefix) is to encode arbitrarily
 nested arrays of binary data, and RLP is the main encoding method used
 to serialize objects in Ethereum. The only purpose of RLP is to encode
 structure; encoding specific atomic data types (eg. strings, ints,
 floats) is left up to higher-order protocols; in Ethereum integers
 must be represented in big endian binary form with no leading zeroes
-(thus making the integer value zero be equivalent to the empty byte

 RLP values are distinguished by a type tag. The type tag precedes the
