 The nghttp Instruction
 =============================
-    
+
 This is an implementation of the Hypertext Transfer Protocol version 2 in C.
 
 The framing layer of HTTP/2 is implemented as a reusable C library.
 
 An HPACK encoder and decoder are available as a public API.
 
-- The nghttp support many different processor, but for the most part you only need the following functions:

 If you are following TLS related RFC, you know that NPN is not the standardized way to negotiate HTTP/2. NPN itself is not even published as RFC. 
 
 The standard way to negotiate HTTP/2 is ALPN, Application-Layer Protocol Negotiation Extension, defined in RFC 7301.
